Problems solved by technology

[0004] Tianmingjing lactone is a plant-derived pesticide. Although it has the advantages of low toxicity, environmental safety and long-lasting effect, it also has the disadvantages of slow effect and high price; Jinggangmycin is a relatively mature pesticide. Pathogenic bacteria have developed resistance to it to a certain extent. In order to rejuvenate it and further prolong its vitality in the market, and to obtain more drugs that can improve drug activity, reduce the amount of application and be friendly to the environment, For the pesticide mixture formula with low toxicity to humans and animals, the inventor screened out the bactericidal composition of Tianmingjing lactone and Jinggangmycin after many tests. Significantly improved control activity and low toxicity to mammals, it is a safe and effective pesticide mixture formulation, and has a good prospect in the development of agricultural fungicides

Embodiment 1

[0021] Embodiment 1 water dispersible granule

[0022] Raw material composition: 1% Tianmingjing lactone ketone, 20% Jinggangmycin, 8.5% alkyl naphthalene sulfonate, 4% sodium lauryl sulfate, 0.8% glycerol, 2% xanthan gum, diatoms Make up the balance with soil, send the active ingredient, dispersant, wetting agent, disintegrating agent and filler into the jet mill to crush to the required particle size, add binder and other auxiliary ingredients, and granulate after fully mixing. After drying, the water-dispersible granules can be obtained.

Embodiment 2

[0023] Example 2 water dispersible granules

[0024] Raw material composition: Tianmingjing lactone 2%, Jinggangmycin 30%, sodium lauryl sulfate 9.5%, pull open powder-BX 8.5%, bentonite 3.5%, gum arabic 1.5%, diatomaceous earth to make up the balance , send the active ingredient, dispersant, wetting agent, disintegrating agent and filler into the jet mill to crush to the required particle size, add binder and other auxiliary ingredients, mix thoroughly and then granulate, and dry it The water-dispersible granules were obtained.

Embodiment 3

[0025] Embodiment 3 water suspending agent

[0026] Raw material composition: Tianmingjing lactone ketone 4%, Jinggangmycin 40%, calcium lignosulfonate 13.5%, pull open powder-BX 7.5%, polyoxypropylene glyceryl ether 1.5%, xanthan gum 3%, urea 1.5% %, deionized water to make up the balance, put the dispersant, wetting agent, defoamer, thickener, and antifreeze into the high-speed shearing machine and mix thoroughly, add the active ingredient and ball mill until the particle size meets the requirements Requirement, add deionized water to make up 100%, promptly make described water suspension.

Abstract

The invention provides a fungicidal composition and belongs to the technical field of pesticides. Effective components of the fungicidal composition comprise carabrone and validamycin, wherein the weight ratio of carabrone to validamycin is (1 to 80)-(80 to 1). The fungicidal composition can be used for preventing and treating common plant diseases and has excellent effects of treating wheat powdery mildew, grape downy mildew, botrytis cinerea, venturia pirina and apple powdery mildew; the action effect of the fungicidal composition is obviously superior to the action effect of single application of the effective components; the lasting period is prolonged; the resistance of the pathogenic fungi is delayed; the fungicidal composition is safe to mammals.

Description

technical field [0001] The invention belongs to the field of pesticide fungicides, and in particular relates to a fungicidal composition with Tianmingjing lactone and Jinggangmycin as active ingredients and its application in preventing and treating fungal diseases of plants. Background technique [0002] Tianmingjing lactone is a sesquiterpene lactone compound, which can be extracted from the roots, stems and leaves of the Asteraceae plant. Preliminary studies have shown that it has the functions of eliminating phlegm, clearing away heat, hemostasis, and detoxification. Medicinal activity, also has insecticidal and bactericidal activity in agriculture, and has a good control effect on common plant diseases such as wheat powdery mildew and wheat take-all. [0003] Jinggangmycin is an agricultural antibiotic developed by the Shanghai Pesticide Research Institute in the 1970s. It is produced by actinomycetes and has strong systemic properties. Inhibit the growth and developme...
