AI Technical Summary

Problems solved by technology

Serious damage to cucumber, celery, pea, cabbage, potato virus-free seedlings, etc., resulting in reduced production or even no harvest
Because Liriomyza sativus has great mobility, it reproduces rapidly in three states of eggs, larvae and adults, and the interval between generations is unclear, so it is difficult to grasp the timing of prevention and control. It is difficult for general drugs to reach the microenvironment where the larvae live and reduce the control effect ; Even if some medicines (comprising microbial insecticides) have better control effects, due to the impact of environmental factors, the larvae killing rate cannot reach 70%, and a single medicine can easily cause pest resistance to medicines, resulting in fewer medicines to choose from , poor control effect
Because microbial pesticides are greatly affected by natural conditions, especially temperature and humidity, they should be used with caution, and the timing of application must be grasped. Biopesticides are slow in killing insects and need to be combined with other control methods.
The main reason for the poor insecticidal effect of existing drugs is their low specificity

Abstract

The invention discloses a pesticide for preventing and controlling Liriomyza spp and a preparation method thereof. The pesticide is prepared from the following components in parts by weight: 50-60 parts of dipterex, 160 parts of vegetable fly eradication gum sugar and 15000 parts of water, wherein the vegetable fly eradication gum sugar is prepared from the following components in parts by weight: 20-25 parts of sodium dodecyl benzene sulfonate, 100-200 parts of edible white sugar, 40-50 parts of pigskin extract and 15000 parts of water. The pesticide has the beneficial effects that higher specificity is achieved, and over 90 percent of Liriomyza spp larvae can be killed within a short time; plants treated by the pesticide can effectively prevent the generation of the Liriomyza spp, harm to the plants is lowered, and the survival rate thereof is increased; because of the ratio of the new pesticide and the synergistic effect of the various components of the pesticide, the pesticide is not influenced by original drug resistance, and the drug resistance is lowered.

Description

technical field [0001] The invention relates to the field of pesticides, in particular to a pesticide for preventing and controlling Liriomyza sativae and a preparation method thereof. Background technique [0002] Liriomyza ( Liriomyzaspp ) Belongs to Diptera, Mansocera, Liriomyidae, and Phytomyridae. There are more than 300 known species in the world, all over the geographical distribution of animals, and the species in the northern temperate zone are the most abundant. At present, there are 15 species of Liriomyza sativae known in my country, among which Liriomyza sativae and Liriomyza sativae are the most harmful in my country. [0003] Liriomyzae (including Liriomyza sativae) is a resistant pest. Its hazards are wide, occur quickly, disasters are serious and difficult to prevent and control. The larvae are mainly harmful to crops such as Cucurbitaceae, Compositae, Leguminosae, Cruciferae, Umbelliferae, and Solanaceae. It is seriously harmful to cucumber, celery, pe...
