Problems solved by technology

For example, the production cost of spirotetramat preparation is relatively high in field use; cyromazine, as a chemical pesticide, has a good control effect on pests at present, but in order to improve the control effect of pesticides on pests, farmers continue to increase the use of pesticides. In addition, pests are prone to develop resistance to pesticides

Abstract

The invention relates to a pesticide preparation for preventing and treating liriomyza sativae blanchard and bemisia tabaci, and belongs to the technical field of pesticide preparation. A pesticide preparation containing spirotetramat for preventing and treating liriomyza sativae blanchard and bemisia tabaci comprises the following effective components in percentage by weight: 5.0%-30.0% of spirotetramat, 5.0-30.0% of cyromazine, and the balance of adjuvant, wherein the pesticide preparation is an emulsion in water or a suspending agent. The emulsion in water or the suspending agent is prepared from a primary agent and the adjuvant, so that the pesticide preparation is capable of efficiently and thoroughly killing injurious insects, and is less in environmental pollution, low in production cost, and suitable for chemical prevention and treatment of liriomyza sativae blanchard and bemisia tabaci.

Description

technical field [0001] The invention relates to the preparation of a pesticide preparation for controlling Liriomyza sativae and whitefly, and belongs to the technical field of pesticide preparation. Background technique [0002] Liriomyza spp is a pest belonging to the Liriomyza family Diptera. It was introduced into my country from Brazil in 1993, and it occurs all over the country at present. Both adults and larvae can cause damage. The female adult flies and stabs the leaves of the plant for feeding and laying eggs. The larvae sneak into the leaves and petioles to cause damage, forming irregular snake-shaped white insect passages, destroying chlorophyll, affecting photosynthesis, and damaging plants. The leaves fall off, causing flower buds and fruits to be burned, and seriously destroying seedlings, mainly damaging more than 110 kinds of plants in 22 families such as cucumbers, tomatoes, eggplants, peppers, cowpeas, broad beans, soybeans, kidney beans, watermelons, wax...
