Recovery Of Endosulfan From Pigeonpea, Chickpea, And Groundnut After Spraying With Different Appliances
The recovery from pigeonpea [Cajanus cajan], chickpea [Cicer arietinum] and groundnut following application of endosulfan at 1.16 g a.i./m² with a hand-operated knapsack sprayer (500 litres spray liquid/ha), a motorized knapsack sprayer (250 litres/ha) and a hand-held spinning disc controlled droplet applicator (CDA) (10 litres/ha) were determined in studies in Andhra Pradesh, India. The percentage recovery of endosulfan on all crops was higher with the CDA (79-85%) than with the motorized knapsack (60-73%) or the hand-held knapsack (38-57%).
