RAINFED RICE A SOURCEBOOK OF BEST PRACTICES AND STRATEGIES IN EASTERN INDIA<br />

Banned pesticides<br />

The following pesticides are banned in<br />

India as per notification of the Government<br />

of India letter no. 8-20/97-CIR II dated<br />

August 19, 1997.<br />

Aldrin<br />

Dieldrin<br />

Calcium cyanide<br />

Chlordane<br />

Copper aceto<br />

arsenite<br />

Dibro mochloropropans<br />

(DC CP)<br />

Endrin<br />

Ethyl mercury<br />

chloride<br />

Ethyl parathion<br />

Heptachlor<br />

Menazon<br />

Nicotine sulphate<br />

manufactured in<br />

India for export<br />

272<br />

Nitrofon<br />

Paraquat<br />

dimethyl<br />

sulfate<br />

Pentachloronitrobenzene<br />

(PCNB)<br />

Pentachlorophenol<br />

(PCP)<br />

Phenyl mercury<br />

acetate (PMA)<br />

Sodium<br />

methane<br />

arsonate (SMA)<br />

Tetradifon<br />

Toxaphene<br />

BHC<br />

Besides arsenic, nitrite poisoning which<br />

comes to the groundwater from urea fertiliser<br />

has posed a direct threat to human lives.<br />

Urea is converted to nitrate.<br />

Nitrate is converted to nitrite and this nitrite<br />

comes to the drinking water to an extent of<br />

1000 ppm, causing acute problems in<br />

human beings such as child blindness,<br />

hepatic ulcer, uterine and breast cancer,<br />

drying of bone marrow and cirrhosis of liver.<br />

Not only pesticides but also agrochemicals may<br />

pollute the drinking water, in both villages and<br />

towns, particularly for poor people with low protein<br />

intake who are prone to these types of problems.<br />

This problem can be mitigated by oxidation of ,<br />

nitrite-contaminated drinking water through<br />

multilayer algal groups or three layers of lime in<br />

overhead tanks.<br />

Integrated pest management (IPM) - an eco-friendly<br />

approach<br />

One scientific approach to counter pesticide hazards is the use of IPM. It is<br />

the integration of cultural and mechanical methods, use of natural<br />

products, behavioural approaches, conservation and augmentation of<br />

biological agents and need-based chemicals.<br />

Cultural practices on IPM<br />

Use healthy seeds.<br />

Grow resistant/tolerant varieties.<br />

Use summer deep ploughing.<br />

Destroy crop residues.<br />

Follow proper sowing time and method.<br />

Use crop rotations to check pest growth.<br />

Maintain optimum plant density.<br />

Follow inter-cropping.<br />

Grow trap crops and carrier crops.<br />

Avoid excessive irrigation and fertilisation.<br />

Use water-logging in summer season to kill soil-borne pests and<br />

pathogens.
