Description
technical field
The present invention relates to a kind of insecticides, be specifically related to a kind of Pesticidal combination that contains the bacillus thuringiensis,Bt control snout moth's larva of rice.
background technology
The representative that thuricade-1 (being B.t class preparation) is microorganism insecticide, can prevent and treat the various pests such as cabbage caterpillar, diamond-back moth, rice plant skipper, rice leaf roller, palaearctic sweet potato, oriental tobacco budworm, cotton bollworm, moths attracted by lamplight.Have and be widely used, noresidue, free from environmental pollution, to the advantage such as people and animals, natural enemies security, but the activity of this medicament and stability are affected by environment large; Must enter in insect bodies through the process of eating could kill insects, is difficult to kill pierce in plant corpus and result of use that certain one-phase that the insect of root can only grow insect just have; Insect can produce and do the property of medicine rapidly under its successive selection pressure.Therefore undesirable because of its field result of use, preventive effect is unstable, the longevity of residure is short, and desinsection speed waits these shortcomings slowly, brings certain difficulty to application work.
