Problems solved by technology

In recent years, with the increase of fertilization and harvest maturity of flue-cured tobacco, the disease has become more serious, and the incidence rate of serious fields is as high as 80%. There are hundreds of diseased spots on each tobacco plant, resulting in a decline in the quality of tobacco leaves , causing great losses to flue-cured tobacco production
However, there are not many effective agents for the prevention and treatment of tobacco red spot disease, and long-term use of a single agent will produce drug resistance

Embodiment Construction

[0051] 90% trichlorfon mixed with water 500 times plus 40% sclerotia copper mixed with water 500 times, and then mixed evenly by 1:1. When the red spot disease gradually increases after the topping of flue-cured tobacco, use a knapsack sprayer to spray evenly on the front and back of the tobacco leaves.

Abstract

The re-compounded farm chemical preparation for preventing and controlling tobacco diseases and pests is one kind of pesticide connecting organic compound. Tobacco aphid and tobacco bakanae disease are main epidemic pest and disease affecting tobacco production in Yunnan, and the present invention provides re-compounded farm chemical preparation for preventing and treating tobacco aphid and tobacco bakanae disease in high effect, less application times and low cost. The re-compounded farm chemical preparation is re-compounded with Anthon and sclerotium copper in the ratio of 2-2.5 mg to 1 liter through homogeneous mixing. The lab and field experiments proves its outstanding tobacco aphid preventing and tobacco bakanae disease treating effect, as well as high its use efficiency, low use amount and low cost.

Description

Technical field [0001] The invention belongs to pesticides containing organic compounds, in particular to pesticides containing organic compounds for preventing and controlling tobacco diseases and pests. Background technique [0002] Due to concerns about human health and environmental protection and pesticide resistance caused by tobacco diseases, more stringent requirements have been put forward for new pesticides for registration. Therefore, the cost of pesticide development has been increased, the development cycle has been prolonged, and people are forced to To focus on exploring the potential of those pesticides that have been used for a long time with high efficiency, low toxicity and low price. [0003] Trichlorfon (trichlorfon) is a phospholipid insecticide, which decomposes into dichlorvos when it encounters alkali. It has stomach poisoning and contact killing effects on insects, and is suitable for pest control of crops such as...
