Residues of systemic insecticides in potatoes

Residues of systemic insecticides in potatoes

Pesticides (Bombay) 14(8): 12-16

Chemical control schedules involving application of phorate granules 0.75, 1.5 and 2.0 kg/ha at 1st earthing and oxydemeton-methyl spray 150, 300 and 400 g/ha per spray treatment, 4-5 times at 10-12 day intervals; aldicarb granules 1.0 and 1.5 kg/ha at 1st earthing for control of aphid vectors were evaluated from residues angle. Another schedule involving application of aldicarb 2.0, 3.0 and 4.0 and 1.0, 2.0, 3.0, 4.0 and 5.0 kg/ha at planting for control of aphids at lower doses (1.0-2.0 kg/ha) and for control of nematodes of potatoes at higher (3.0 to 5.0 kg/ha) doses was also evaluated for residues. Phorate residues resulted from all 3 doses on/in unwashed and unpeeled and unwashed and peeled potatoes above the tolerance limit of 0.5 ppm up to 54-65 days following application in soil. Oxydemeton-methyl residues above the tolerance limit of 0.2 ppm persisted up to 22-23 days following last spray treatment on/in such potatoes. Excessive residues of aldicarb persisted up to 55 days during spring from both doses (1.0 and 1.5 kg/ha) dose in autumn on/in unwashed and unpeeled potatoes. Doses of aldicarb up to 3.0 kg/ha were safe from residues by observing a waiting period of 90 days between granule application and harvesting. Peeling and washing of potatoes could decrease residues of toxicants to a considerable extent. Except in few cases where insecticide residues were within tolerance limits, processing (washing, boiling, peeling) of potatoes decreased residues to non-detectability levels. Aldicarb residues (4.0 and 5.0 kg/ha) applied at planting dissipated within tolerance limit or to extent of undetectability levels even in unprocessed (unwashed and unpeeled) potatoes harvested 90 days after aldicarb application and stored for 30 and 60 days in jute bags at room temperature in ordinary stores.
