棉花蚜、螨群集在棉叶背面刺吸汁液,危害棉花,两者既相互竞争又相互制抑,最终处于平衡状态.由于速灭菊酯对蚜、螨药效的差异,破坏了这种平衡,造成在大量消灭蚜或螨的同时,剩余的螨或蚜大量增殖,造成再猖撅.丰收菊酯对两种害虫均有优异的防效,可基本保持原有的共存平衡状态,没有再猖撅现象. Cotton aphid and mite cluster punctures the juice on the back of the cotton leaf and endangers the cotton, both of which compete with each other and restrain each other at equilibrium. As a result of the differences in potency of velvet to aphids and mites, the balance is destroyed , Resulting in a large number of elimination of aphids or mites at the same time, the remaining large mites or aphids proliferate, causing re-rampant. Enrichment Juice both excellent pest control effect, can basically maintain the original state of coexistence and balance, no longer Rampant phenomenon.
