The insecticide application effect on combating of pea weevil larvae (Bruchus pisorum L.) during the cultivation of Milwa peas

摘要

A com. thiacloprid and deltamethrin-contg. insecticide was used (doses 0.750 L/ha or 0.375 L/ha) either (i) during seed maturation or (ii) after exceeding the economic harmfulness threshold in exptl. crops in 2015-2016 in order to optimize dose size and spraying period. The use of 0.750 L/ha dose in the second variant was the most effective.
