Technical Field

The invention relates to the technical field of compound synergistic bactericides, and in particular relates to a pesticide composition containing brassinolide compounds, pyraclostrobin and thiamethoxam and application thereof.

Background

Thiamethoxam is a second generation nicotine high-efficiency low-toxicity insecticide with a brand-new structure, and can block normal conduction of a central nervous system of insects, so that pests die when paralytic attack occurs. The insecticidal composition has the characteristics of contact poisoning, stomach toxicity and systemic activity, higher activity, better safety, wider insecticidal spectrum, high action speed, long lasting period and the like, has high activity on coleoptera, diptera and lepidoptera pests, particularly homoptera pests, and can effectively prevent and control various aphids, leafhoppers, plant hoppers, whiteflies, scarab larvae, potato beetles, nematodes, ground beetles, leaf miners and other pests which generate resistance to various chemical pesticides. The method can be used for stem leaf treatment, seed treatment and soil treatment. Suitable crops are rice crops, sugar beet, rape, potato, cotton, kidney bean, fruit trees, peanut, sunflower, soybean, tobacco, citrus and the like.

Pyraclostrobin is a novel broad-spectrum bactericide. The mechanism of action is by inhibiting mitochondrial respiration, rendering mitochondria unable to produce and supply energy (ATP) required for normal cellular metabolism, ultimately leading to cell death. Has the functions of protection, treatment, leaf penetration and conduction, strong systemic absorption and the like. The bactericidal composition is widely used for preventing and treating diseases caused by almost all types of fungal pathogens such as ascomycetes, basidiomycetes, deuteromycetes and oomycetes on wheat, barley, soybean, peanut, grape, vegetables, potato, banana, lemon, coffee, fruit trees, walnut, tea trees, tobacco, ornamental plants, lawn and other field crops, and has better preventing and treating effects on powdery mildew of cucumber, downy mildew, banana scab, leaf spot, sclerotinia and the like.

The brassinolide compound is a novel green environment-friendly plant growth regulator, can promote the growth of crops such as vegetables, melons, fruits and the like through seed soaking with proper concentration and stem and leaf spraying treatment, can improve the quality of the crops, can improve the yield of the crops, can also improve the drought resistance and cold resistance of the crops, and can relieve the symptoms of plant diseases and insect pests, phytotoxicity, fertilizer injury and freezing injury of the crops. The brassinolide compound is a plant endogenous hormone, has high biological activity, widely exists in organs such as pollen, seeds, stems, leaves and the like of plants, is harmless to human and livestock, and has safe and effective normal dosage.

Zeaxanthin, also known as "zeaxanthin," is a lipid-soluble pigment component of lutein, a dihydroxy derivative of beta-carotene. Zeaxanthin is abundantly present in plant tissues such as green vegetables, corn seeds, lycium barbarum and physalis alkekengi fruits and some non-photosynthetic bacteria. Has poor light and heat stability, strong oxidation resistance and Fe resistance³⁺And Al³⁺Is also less stable, but against other ions, acids, bases and reducing agents Na₂SO₃Etc. are relatively stable.

D-panthenol, which is colorless to yellowish, transparent and viscous liquid, has light and special odor and is insensitive to light, oxygen and heavy metals, and is used as a nutritional supplement and an enhancer.

In the existing production field of pesticide preparations, no report exists on the preparation of pesticide preparations by compounding a brassinolide compound, pyraclostrobin and thiamethoxam into a pesticide active ingredient, mixing D-panthenol, zeaxanthin and houttuynia cordata extract to prepare a pesticide synergistic growth promoter and combining the pesticide active ingredient and the pesticide synergistic growth promoter.
