Effect of defoliants on numbers of sucking pests and predators in cotton fields

Zashchita Rastenii Moskva ( 11): 32-33
Effect of defoliants on numbers of sucking pests and predators in cotton fields
Investigations in the Samarkand region of Uzbekistan showed that Gemetrel or Khaet (both of unstated composition) applied when 2-3 bolls on average had opened per cotton plant (optimum dose 8-10 litre and kg/ha, resp.), was less toxic both to pests (aphids and cicadellids) and to predators (e.g. chrysopids and coleopterans) than was magnesium chlorate used as a standard.
