20. Ethion Used for the control of aphids and mites Impaired memory and concentration, disorientation, severe depression, irritability, confusion, headache, speech difficulties, delayed reaction times, nightmares, sleepwalking, and drowsiness or insomnia. An influenza-like condition with headache, nausea, weakness, loss of appetite, and malaise
21. Acephate It is a systemic insecticide effective against chewing and sucking pests. It is a possible human carcinogen and evidence of mutagenic effects and reproductive toxicity.
22. Fenvalerate It act contact and stomach poison. It controls the pests on crops of cotton, vegetables and fruits. Reduction in weight.
23. Permethrin It is a stomach and contact insecticide effective against broad range of pests of cotton, fruit and vegetable crops. Health risks found include genetic damage - cancer potential - neurotoxic dangers to unborn children - and harm to marine life.
24. Cypermethrin It is a stomach and contact insecticide effective against broad range of pests of cotton, fruit and vegetable crops. Cypermethrin is a possible human carcinogen.
25. Deltamethrin It is a potent insecticide effective as a contact and stomach poison against broad range of pests of cotton, fruit and vegetable crops and store products. Potential endocrine disrupter
26. Carbaryl It is a contact insecticide and fruit thinner with a broad spectrum of activity effective against many pests of fruits, vegetables and cotton. It is also used to control earthworms and leather jackets in turf. Carbaryl may cause mutations (genetic changes) in living cells. It is a possible teratogen & may damage the kidneys and nervous systems. Within the stomach produces N-nitrocarbaryl, a well known carcinogen, Non-hodkins Lymphoma, brain cancer.

It is effective for control of aphids, nematodes,flea beetles, leaf miners, thrips and white flies on a wide range of crops. Aldicarb is a cholinesterase inhibitor and so can result in a variety of symptoms including weakness, blurred vision, headache, nausea, tearing, sweating, and tremors.

Simazine &Atrazine It is a persistent soil acting herbicide which in high concentrations acts as total weed killer and in lower concentrations is used for selective control of germinating weeds in a variety of crops - maize, sugarcane, pineapple, sorghum. It is also used for long term control of annual grass and broad-leaved weeds in crops like citrus, coffee, tea and cocoa. Cancer of testes
34. Glyphosate It is a potent non-selective post emergence herbicide which kills mono and dicotyledonous annual and perennial weeds No adverse effects.
35. Isoproturon It is used to control annual grass weeds in wheat rye and barley. Isoproturon appears to be a tumour promoter rather than a complete carcinogen.
36. Trifluralin It is used for the control of annual grasses and broad leaved weeds in a wide range of crops cotton, groundnuts, soyabeans, brassica, beans an cereals. Prolonged or repeated skin contact with trifluralin may cause allergic dermatitis . Other effects include decreased red blood cell counts and increases in methemoglobin, total serum lipids, triglycerides, and cholesterol. It has been shown to cause liver and kidney damage in other studies of chronic oral exposure in animals .
37. Mancozeb It is a protective fungicide, effective against a wide range of foliage disease. Ethylenethiourea (ETU) in the course of mancozeb metabolism and production has the potential to cause goiter, a condition in which the thyroid gland is enlarged, this metabolite has produced birth defects and cancer in experimental animals
38. Captan It is a foliage fungicide with protective action . It is mainly used for seed treatment and soil fungicide. Captan is a possible carcinogen and mutagen
39. Captafol It is a protective, wide spectrum foliage and soil fungicide. Captafol has oncogenic potential (potential to cause cancer)
40. Carbendazim It is a systemic fungicide which controls wide range of pathogens of cereals , fruits, grapes ornamentals and vegetables. It is very effective against leaf and ear disease of wheat. It disrupts the production of sperm and damages testicular development in adult rats. Carbendazim is also a teratogen ­ damaging development of mammals in the womb.
