| Popis: | Pirimiphos methyl when sprayed at dosages of 10 and 15 p.p.m., effectively protects dehusked maize in cribs for 3 months against incipient or cross infestation by stored product insects. Longer storage would however require a reapplication of the insecticide. At 5 p.p.m., pirimiphos methyl is not a protectant against insect infestation of maize stored beyond 1 month. As insect numbers and grain damage increased, viability of infested maize decreased. Only when grain embryo is damaged or endosperm destroyed can insect infestation prevent grain germination. |
