摘要: Abstract To assess the protection against cabbage root fly larvae achieved in cauliflower crops by filmcoating seed with insecticide, six field experiments were carried out between 1990 and 1991. Various dosages of insecticides tested at four widely separated locations The Netherlands high moderate population densities fly. plants raised ‘loose-filled cells’ peat ‘blocks’, or as peg plants. efficacy formulations isofenphos, chlorpyrifos fonofos, two three filmcoating, compared a conventional post-planting treatment. Filmcoating fonofos was less effective controlling than Chlorpyrifos 28.8 g a.i. kg−1 isofenphos 30 consistently gave good control treatment each plant.
