Abstract
PESTAB. X-factor and premium grade X-factor (a byproduct of lindane manufacture) were incorporated as drench at 0 and 10 ppm levels to mud pots, containing 7.5 kg of soil. Tap water was added to bring the moisture to about 60% water-holding capacity of the soil, and moisture was maintained at that level. French bean and tomato seeds were sown in these pots. Both test chemicals failed to significantly affect growth or nutrient uptake in the French bean plant. Residual analysis did not reveal any parent molecule in the plant body, possibly due to phytodegradation of the absorbed chemicals. Both chemicals inhibited root growth by approx 35-42% and shoot growth by 22%. Except for stunted growth, plants in treated pots showed no symptoms of phytotoxicity. Weight reduction was high, amounting in 75% in both shoot and roots. Rate of nutrient uptake increased by about 45% when X-factor was present and 35% with premium grade X-factor. Results suggest that tomato plants either have the ability to absorb more of the candidate chemicals or have poor detoxification mechanisms. In the uncropped soil about 20-25% of the original dose had disappeared in 3 wk. After the same time period 55-60% of the applied dose had disappeared in cropped soil. The findings suggest the possibility of using French bean, paddy, ragi, and brinjal as rotation crops in soils containing chlorinated pesticides.
