Embodiment 1

[0058] Example 1 Research on the Composite Performance of Thiamethoxam, Diazinon and Difenoconazole

[0059] Compound thiamethoxam, diazinon and difenoconazole according to a certain ratio, and carry out the experimental detection of insect control and sterilization. After being immersed in the solution for 10 seconds, use filter paper to absorb the excess medicinal solution, transfer the tested worms to raise under normal conditions, repeat 4 times for each treatment, and soak 20 worms each time; The petri dish with nutrient substances was cultured, and the compound drug was evenly dropped on the flora, and the growth of the colony was observed after a period of time. The two experiments were respectively set without the treatment of the drug as a control.

Abstract

The invention relates to the technical field of pesticide, and especially relates to a pesticide composition, a sustained-release pesticidal fertilizer, and preparation methods thereof. The pesticide composition comprises a bactericide and an insecticide. The bactericide is difenoconazole, and the insecticide is composed of thiamethoxam and diazinon. The sustained-release pesticidal fertilizer provided by the invention has the advantages of high activity, good efficacy, and significant fertilizer effect. The sustained-release pesticidal fertilizer has dual effects as a pesticide and as a fertilizer, and can fully perform insecticidal, bactericidal and fertilization functions. With the fertilizer, pesticide and fertilizer sustained release is realized. The pesticidal fertilizer is effective for a season with one application.

Description

technical field [0001] The invention relates to the technical field of pesticides, in particular to a pesticide composition, a slow-release medicinal fertilizer and a preparation method thereof. Background technique [0002] Rice is native to tropical Asia, and after being widely planted in China, it gradually spread to all parts of the world. The fruit of paddy rice is rice paddy, and paddy paddy is called rice, fragrant rice, rice after shelling. Nearly half of the world's population feeds on rice. In addition to being edible, rice can also be used as industrial raw materials for wine making and sugar refining, and rice husk and rice straw can be used as feed. [0003] In the rice planting process, common pests mainly include Homoptera pests (typical pests include rice planthopper, whitefly, etc.) and Lepidoptera pests (typical pests include rice stem borer, rice leaf roller, etc.). Among them, rice planthoppers damage rice and other crops by piercing and sucking plant ...
