CURRENT COMMENTS - COTTON FARMER OF ANDHRA PRADESH: THE LATEST VICTIM OF CHEMICAL FARMING

A spate of suicides by farmers in the cotton belt of Parkas District in coastal Andhra Pradesh is yet another evidence of the failure of chemical farming. Lured by high yielding varieties of cotton and promise of huge profits farmers took to it in a big way some years ago. Guntur and Parkas districts were traditional tobacco areas but after the erratic experience with the tobacco crop which is a near monopoly of the Indian Leaf Tobacco Development Corporation the farmers took to cotton and found the going quite good. It is an important commercial crop in Andhra Pradesh grown over an area of 5-6 laky hectares with an annual production of 8-10 laky bales of 170 legs each in the state. Guntur district accounts for 1.62 laky hectares and Parkas District 7296 hectares -Le. about'47% of cotton area in the state.

Cotton is a finicky crop but if the farmer nurses it with care and devotes constant attention he is assured of a good yield and income. While farmers with large holdings were unable to devote much time, attention and money to the crop the small growers owning one or two acres played for high stakes by taking on lease land from bigger farmers and raising cotton.

In the year 1987-88 cotton crop suffered very badly due to prolonged dry spell during the early vegetative phase in Parkas and Guntur districts. Inadequate rains during Sharif 1987 followed by 3 successive cyclones in October and November 1987 damaged the crop considerably. This was further followed by widespread heavy attack of American bookworm (Hetiothis armigtm) in November - December 1987 in Guntur and Parkas districts. Adding fuel to the fire was the disastrous attack by the whitefly (Bemisia tabaci gent). It is also reported that there was a large scale sale of spurious or adulterated pesticides. As it is the "budworm" had developed resistance to pesticides in use. The result was* catastrophic. In Parkas District alone nearly 8000 hectares of cotton crop was removed without any pickings and in the remaining area, yield had come down to 2-3 qumUWhcctare as against the normal yield of 14-16 quintals/hectare (see Table 1 and 2).

In December the "Death Harvest" began when the desperate farmers and their families took to pesticides that could not save their crop. The official death toll is 30 whereas there are claims that it may be much more.

Earlier reports indicate that the Hefiotms caused considerable damage to cotton (38%) in the year 1977-78 during December after cessation of cyclonic rains in November and in the subsequent year (1978-79) during the month of January. Since then the damage caused by( the pest was negligible and controlled by recommended inscribes. In 1984-85 whitefly became a serious pest and caught the attention of scientists and cotton growers. Several chemicals and plant products were identified for effective whitefly control and while gaining confidence in the management of whitefly the overlapping occurrence of Halitosis outbreaks’ during this year caused extensive damage to cotton crop resulting in heavy losses. Halitosis occurred on cotton as early as in August and continued with heavy populations throughout crop growth,’ A single cotton plant harbored as many as 7-18 larvae in between November and January months of 1987-88 compared to 0.1 - 4 in the previous years

Several causes have been attributed to the sudden outbreak of Halitosis on cotton in Andhra Pradesh. Pigeon pea suffered heavily due to severe attack of Halitosis in 1986-87. Proper plant protection measures are lacking for pigeon pea and hence the residual population of Halitosis on the pigeon pea crop was carried over to cotton crop of 1987-88 season through summer hosts particularly tomato, bendy etc. The pest population occurred much earlier in the cotton crop than the normal period (October - November). These were ignored by cotton growers without taking proper control measures due to severe drought resulting in very poor crop growth. Timely spraying operations against these pests could not be undertaken due to scarcity of water in many villages. Hence pests multiplied during early part of the season and by the time the crop recovered from drought, following cyclonic rains' during October the pest population reached an unmanageable level All attempts made to contain the pest outbreak with recommended insecticides were found futile.

The excessive and improper use of plant protection chemicals over several years has been the chief culprit of the pest outbreak. It is reported that in Southern India more than 26 species of parasites feed on Halitosis. Also several predators like birds, spiders, bugs, mantis, earwigs, and ants eat the eggs, larvae pupae and the moth of the insect. The natural enemy component was almost non-existent in any of the eco-systems where severe outbreak of the pest was noticed. The repeated and discriminate use of some of the most persistent insecticides like DDT along with synthetic pyrethorid components literally wiped away many of the natural enemies. Predation by birds was also not observed as the poisoned insects might have affected the vertebrate predators or the birds might have been scared away from the pesticide treated areas.

The choice of pesticides, dosage, number of rounds applied methods of application were also not adopted scientifically. 3 or 4 insecticides were even applied together as tank mix often at sub lethal doses and applied on cotton. After seeing the total failure or inadequate control the farmers started applying heavy doses. Pesticides were applied even 30-40 times as a result of which the pests developed high resistance to these pesticides.

Application of pesticides with battery operated UDV sprayers might have killed natural enemies drastically. The defective application methods resulted in application of concentrated. pesticides on some plants and only water on others. Several improper spray delivery systems like 'Akola' pump sprayer which applied the chemical spray fluid on top of the plants allowing run off and drop of the chemical and improper coverage of the entire plant were also responsible for poor efficacy of chemicals applied.

Many High Yielding varieties are highly susceptible to the pest. Staggered savings particularly under irrigated condition, extending the crop duration by continuous irrigation, rationing and poor crop refuse destruction are also important factors attributed to the outbreak of the pest on cotton. Pest problem was also acute in areas where there were no closed season in the year.

Monocropping led to the deterioration in quality and yields. Monocropping results in nutritional disorders associated with deficiency of magnesium, nitrogen, pottasium, phosphorous and other physiological causes. Increased nitrogen application without regard to balanced phosphorous and pottasium application led to high incidence of sucking pests in general and whitefly in particular.

A critical study of the pest populations in five cotton growing areas in Andhra Pradesh was made by Reddy in 1988. Three synthetic Pyrethorids and six conventional insecticides were included in the bioefficacy evaluation at recommended doses. In the case of Guntur population it was observed that only 10% mortality of the larvae caused by cypermethrin monocroptophos, quinalphos, endosulfan and DDT, 20% mortality by deltamctrin, fenvalerate and chloppyriphos and 30% mortality by carbaryi. As was stated earlier the insect had developed resistance and cross resistance to almost all insecticides in Guntur region which may be the result of many years of indicrirninatc use of the pesticides in that area.

The inefficiency of many insecticides was also evident with the populations at Nandiyal, Warangal and Adilabad though not at the same level as in Guntur. But the pest was controlled to an extent of 75-100 in Sreekakulam area where the cotton cultivation is relatively new and pesticide load is far less in the agro-environment. Though DDT is banned for crop protection in our country it is still used for cotton protection in Southern states and this chemical comes from public health sector to the agriculture. Development of many fold resistance in Guntur population to synthetic pyrethroids and endosulfan has been observed. Use of Synthetic pyrethorids has resulted in an unusually high degree of resistance in a large number of insects all over the world. What is more alarming is the fact that insects which develop immunity also develop cross resistance to other pesticides. This means that other effective insecticides used against these pests will become useless in future. The resistance to synthetic pyrethorids occurs in a short time as compared to other chemicals. Use of synthetic pynethorid has also led to the flare up of secondary pest like uphids and mites. In several parts of India mite a secondary pest has become a serious problem.

The Haryana Agricultural University had warned the State Government way back in 1984 against the use of synthetic pyrethroids as they prove to be carcinogenic Ignoring the reports the Punjab Agricultural University purchased Rs.14 crores worth of chemical in 1984. Countries selling synthetic pyrethorids (Japan and United States) to India have banned their use in their own countries.

Several measures have been taken by the Department of Agriculture to control the pests. These include pest surveillance, village level training programmers for the farmers in identifying pests and the control measures, use of whitefly resistant varieties, avoidance of the use of repeated and heavy doses of Synthetic Pyrethroids, alternate cropping pattern to check spread of pests and diseases, and wide publicity through mass media for the proper and efficient use of insecticides. Several quality control measures have been taken by the Andhra Pradesh Government to check the quality of insecticides. Efforts are being taken to curb the menace1 of sale of sub-standard and spurious pesticides. The State Government has also taken several steps to help affected farmers in debt by waiving off loans and offering several subsidies. The problem does not end here. We need to look for a long term solution which is obviously an effective and ecologically sound plant protection measure.

Several species of parasites and predators were reported to attack Halitosis armiger in different parts of die country. Deliberate attempts to mass breed and use them in the field are rather limited. 'Again, biological control through conservation of naturally occurring' parasites, predators and insect pathogens is also very important as they can bring down the pest population by about 60-70 per cent. The usefulness of egg parasites, Trichogfamma spp. the Telenomous spp., egg-larval parasite, Chelonus blackbumi, larval parasities, Complete is cholorideae, Eucelatoria bryani, Eriboms trochanteratus, etc., and pupal parasites, Trichospuus pupivora, Testrastichus Israeli and predators like Chrysopa spp. Menochilus etc, will be highly useful to keep the pest under considerable check. The techniques for the mass I production and field release of these biocontrol agents are already’ available in the country and the heed is to strengthen the extension efforts in this direction. The indigenous Nuclear Polyhedrosis Virus (NPV) proved to be an efficient biological control agent of H. armiger. Mass culture of this should be encouraged. National regulatory bodies should develop a defined practical attitude for development and utilization of microbes. Only then the supply of NPV to the farmers at periodic intervals will be possible. Research on the possible use of plant products like Neem seed kernel extract and Neem oil emulsion for pest protection against pests needs to be intensified.

The tragedy at Andhra Pradesh should be an eye opener to policy makers and supporters of Green Revolution, though much has been talked about Integrated Pest management it seems .today that chemical control/pesticide research takes the major share. We look for alternatives only when chemicals fail Also the rate at which we are decreasing our genetic diversity through hybridization and selection is alarming. We are in a danger wherein the entire crop could be wiped out by some pest and we are left with no new variety to start from Let us wake up before we see the "Death harvest" in several other crops. It is time for us to make a serious analysis of the pest control methods and opt for naturally sound ones!

Recommendations of the Agriculture Section

1. Traditional technology is
   
   a. Natural resource oriented
   b. Location specific and it can be as per farming situation.
   c. Best for soil health and moisture conservation
   d. Takes care of eco-balance and alternate use of land.
   e. Is proving productive and remunerative
   f. Land - livestock - aquaculture based systems can be better developed through traditional technologies.
   g. Present system of passing on the recommendations to the farmers through
   Government extension machinery takes a long time. NGOs can also be oriented:
   h. Extension - subsidy and target oriented approach may not be useful; it has proved
   to be detrimental to development.
   i. Farmers should be made to prepare bankable projects. It is possible under organic farming.
   
   
2. Farmers should spread the message of their success through traditional farming to the immediate neighborhood be it agronomy, plant protection or planting material.
   
   
3. a) Scientists should verify and document traditional wisdom and say whether they
   are workable or not.
   b) Students and young faculty should be more exposed to the traditional farming.
   c) Extension should be renamed as Exchange of information; NGOs should also have an appreciable and respectable role to play.
   
   
4. The Congress recognized the harmful effects of indiscriminate use of chemical pesticides in agriculture and emphasized the need for using alternatives in the context of Integrated Pest Management (IPM). The national policy on implementing IPM should be vigorously followed in all cropping systems.
   
   
5. Over ages the farmers have been adopting many non-chemical methods of pest management and their wisdom in Traditional Agriculture is very significant. Many innovative farmers are continuously evolving better methods of pest management. Much of this is neither scientifically investigated to find out the plausible reasons for their effectiveness nor documented. The scientists in Universities and Research Organizations should undertake such studies.
   
   
6. The best among the traditional practices and non-chemical methods should be blended with the modem techniques and technologies, for sustainable crop production.
   
   
7. The crop varieties which, are resistant to pests and diseases as well as soil and climatic stresses should form the major component of IPM. In remote areas, the farmers are cultivating traditional varieties for centuries in more or less isolated pockets. In addition, we have a rich bio-diversity of gene pools in permanent ecosystems such as forests. Efforts should be intensified to collect these valuable genetic materials and utilize them for evolving resistant varieties.
   
   
8. The choice of the seed, method of storage and the pre-sowing treatments with indigenous materials are important in getting good varieties of the crop and good yield. In the ancient literature on Vrkshayurveda, details on the above are available for many crops. They should be investigated in the present day context and utilized for the benefit of the farmers. Collaborative work with Ayurvedic practitioners is recommended.
   
   
9. In traditional agriculture, polycrop ecosystems are mostly adopted and an ideal crop rotation suitable to the agro-climatic conditions of the location is followed. Monocropping with a narrow genetic base is not sustainable. It is therefore emphasized that work should be further strengthened on suitable intercropping and sequential cropping systems which would minimize the pest and disease load.
   
   
10. Excessive use of irrigation water and chemical fertilizers, particularly nitrogenous fertilizers, has led to outbreaks of pests and diseases in many crops. Hence, there is a need for optimizing the use of these inputs to reduce pest and disease incidence.
    
    
11. Organic manures are needed, for sustainable crop growth and soil health. Pests and diseases are minimum in fields treated with different kinds of organic manures. The farmers should be encouraged to produce enough organic manure at the farm and village levels. Bioconversion of farm / rural / urban / industrial wastes for composting should be adopted for minimizing the use of chemical fertilizers and the damages caused by pests and diseases.
    
    
12. The chemical pesticides have led to several problems such as development of resistance of the pests to pesticides, resurgence of target and non-target pests, tainting and leaving residues of pesticides in food, fodder, feed, water, soil and air, destruction of beneficial organisms such as honeybees, parasites, predators, birds, pollinators, microorganisms, and phytotoxicity to plants besides causing innumerable diseases in human beings and domestic animals. Repeated use of chemical compounds has also resulted in the failure of pesticides in checking the pests. The resource poor farmers of the country cannot afford to use the chemical pesticides in view of the high costs. Hence, the Congress decided to request the concerned authorities to propagate the ideas of IPM and non-chemical methods of crop protection, besides highlighting the drawbacks of the chemical pesticides.
    
    
13. Farmers are using many plant products in pest and disease management. Locally available species such as neem, Karanj, Mahua, Vitex, Ipomea, etc., are used commonly. More species of plants possessing crop protection value should be identified and products developed. Studies are also needed to improve the efficiency of the plant products by the addition of locally available adjuvant.
    
    
14. Natural control of pests by parasites, predators, insect pathogens birds, reptiles some mammals etc, is an important factor in IPM. The balance of life in the ecosystem should not be disturbed and the beneficial species must be conserved for getting the maximum benefit.
    
    
15. Wherever the naturally occurring biological control agents are not adequately present, they should be bred on a large scale, using the local resources and supplied to the farmers for release in the fields.
    
    
16. The farmers should be trained to mass produce the biopesticides at the village level on a. co-operative basis. All encouragement should be provided for the production and use of biopesticides.
    
    
17. There are many cultural, mechanical and physical methods of crop protection which are simple and easy to adopt and are cost-effective. Large scale campaigns should be organized to control pest and disease outbreaks, involving the farmers, schools and college students, teachers, NGOs and Government departments.
    
    
18. In ancient agricultural science, there was a system of predicting the outbreaks of pests and diseases in relation to weather changes in the solar cycle. These methodologies should be investigated and incorporated with the modern techniques for forewarning / forecasting.
    
    
19. The data available from various institutions on insect traps, such as light traps, sticky traps, insect sex pheromone traps, suction traps, fungal spore traps etc, must be documented. Different trap systems should be used to control and monitor pests,
    
    
20. Strategies for achieving the goals of sustainable agriculture with minimum disruption to the agroecosystem must be developed and popularized.
    
    
21. In Animal Husbandry by and large the traditional technology is being practiced by our livestock farmers throughout the "country and farmers experiences-are tested and many of them have also been proved scientifically.
    
    
22. In order to develop better technologies and for exchange of information and materials, the Congress strongly recommends initiating an "All India Coordinated Research and Development Project on Organic Farming and Traditional Agriculture", with emphasis on sustainable crop production, under the aegis of the Indian Council of Agricultural Research (ICAR).
    
    
23. Providing Institutional Support: KEY ISSUES
    
    a. Involvement of scientists for validation and value addition.
    b. Research support to innovative farmers.
    c. System of registration of new ideas and innovation developed by fanners.
    d. Venture capital for local entrepreneurs in developing and commercializing new
    products from local knowledge. ,
    e. Mechanism for promoting contact / interaction between innovative farmers and
    scientists.
    f. Mechanism for compensation to original innovators or community.
    g. Incorporating indigenous knowledge into curriculum and formal education.
