应用高效、低毒杀虫剂对储粮害虫进行毒力及药效测定,证明溴氰菊酯、辛硫磷混用对主要储粮害虫玉米象等,联合毒力高,持效期长,并以此为主要成分,研制出一种适合农户分散储粮使用的谷物保护剂——2％粮种安粒剂。一、室内药效测定结果用实验室加工制剂处理无虫小麦后,接入玉米象成虫,定时观察存活虫数。由表1可见,各处理的校正虫口减退率,以2％粮种安粒剂(溴氰菊酯+辛
The application of high efficiency and low toxicity insecticides on the storage of pests and virulence tests to prove that deltamethrin and phoxim mixed on the main grain pests such as corn, such as joint, high virulence, long duration, and Taking this as the main component, a cereal protective agent suitable for the distributed grain storage of farmers was developed, which is 2% grain seed granule. First, the results of indoor pharmacodynamics Laboratory treatment preparations were used to deal with non-insect-resistant wheat, adult corn access, regular observation of the number of surviving insects. As can be seen from Table 1, each treatment corrected the population decline rate of insects to 2% grain seed capsules (deltamethrin + Xin
