Abstract
The invention discloses a compound tablet pesticide for preventing and treating crop pests at roots and a preparation method for the compound tablet pesticide. The compound tablet pesticide is prepared from the following raw materials in parts by weight: 5-15 parts of animal fat, 35-45 parts of corn starch, 5-15 parts of imidacloprid active compound and 5-15 parts of acetamiprid active compound. The compound tablet pesticide for preventing and treating the crop pests is suitable for prevention and treatment of pests such as greenhouse whitefly, aphids, thrips and liriomyza sativae on crops such as vegetables, fruits, beans and cottons and adopts a root embedding use method; the benefit is that the compound tablet pesticide is embedded at the root of a crop when the crop is planted, so that the pesticide effect is slowly released; the compound tablet pesticide enters the plant through root absorption and then is conducted to respective parts such as stems, leaves and flowers except fruits of the plant through the interior of the plant; due to long-term prevention and treatment, the problems of the insecticide resistance, the insecticide tolerance and high residue content in the prior art are solved, and the dosage is reduced, so that the production cost is reduced, the pesticide residues are reduced, and the environment pollution is alleviated.
Description
technical field [0001] The invention relates to a pesticide, in particular to a compound tablet pesticide for preventing and controlling crop insect pests at roots and a preparation method thereof. Background technique [0002] In recent years, various domestic and imported insecticides are facing major problems such as drug resistance, drug resistance and high residue. In agricultural production, the frequent use of pesticides and the large amount of medication not only waste time, money and material resources, but also lead to higher and higher pesticide residues in crops, polluting the environment and threatening the ecological balance. When the crops are planted, the compound tablet pesticides are applied together with the crops to fill the roots, so that the duration of the drug effect increases, and various crops have no pests that should be controlled for a long time or even a season. According to the summary of farmers all over the country after using it for three ye...
