Problems solved by technology

[0009] Banana Leaf Spot: Occurs in the banana producing areas in southern my country. It is the most important disease of bananas. Anti-oxidant products cannot achieve the ideal control effect, and the dosage is large and the cost is high
[0010] For the prevention and control of resistant bacteria in agriculture, one way is to introduce new varieties. However, the development cost of active ingredients in new varieties is high, the development cycle is long, and the speed of pest resistance can never be compared.
Other methods, such as crop layout adjustment, rotation of different pesticides, etc., have the defect that it is difficult to really achieve obvious effects in the actual operation process

Embodiment 1

[0047] Embodiment 1: prevent and treat powdery mildew

[0048] According to the weight ratio of tridemorph (unless otherwise specified, all refer to mass parts) 20 parts, difenoconazole 15 parts, emulsifier alkylbenzene sulfonate 10 parts, surfactant alkylphenol polyoxyethylene ether 5 parts, 0.3 parts of antifreeze glycerin, 0.3 parts of thickener polyethanol, 0.2 parts of preservative sodium benzoate, 0.3 parts of defoamer silicone foam defoamer, 5 parts of cosolvent xylene, water to 100 parts, It is made into a water emulsion, and the formula is diluted and sprayed by 1500-2500 times, and the control effect in the field is 94.64% within 72 hours after application. In this invention, 70% tridemorpholine aqueous emulsion and 37% difenoconazole aqueous emulsion were used as reference objects, and the control effects were 30.52% and 43.8% respectively after 72 hours of application, which can be seen clearly It is found that the mixed preparation is 2-3 times higher than the si...

Embodiment 2

[0049] Embodiment 2: prevent and treat leaf spot

[0050]According to the weight ratio of tridemorph (unless otherwise specified, all refer to mass parts) 10 parts, difenoconazole 30 parts, emulsifier alkylbenzene sulfonate 11 parts, surfactant alkylphenol polyoxyethylene ether 5 parts, 5 parts of antifreeze glycerin, 0.2 parts of thickener polyethanol, 0.3 parts of preservative sodium benzoate, 0.3 parts of defoamer silicone defoamer, 15 parts of co-solvent xylene, water to 100 parts, It is made into a water emulsion, and the formula is diluted and sprayed by 1500-3000 times, and the control effect in the field is 95.12% within 72 hours after application. In this invention, 70% tridemorphine emulsion in water and 37% difenoconazole emulsion in water were used as the reference object, and the control effects were 40.36% and 38.52% respectively after 72 hours of application. It is found that the mixed preparation is 2-3 times higher than the single-dose control effect of the t...

Embodiment 3

[0051] Embodiment 3: prevent and treat powdery mildew

[0052] According to the weight ratio of tridemorpholine (unless otherwise specified, all refer to mass parts) 29.8 parts, propiconazole 12.5 parts, emulsifier phenethylphenol polyoxyethylene ether phosphate salt 12 parts, solvent xylene make up 100 parts, The emulsifiable concentrate is made, and the formula is diluted and sprayed by 1000-2000 times, and the control effect in the field is 93.09% within 72 hours after application. In this invention, 70% tridemorphic emulsifiable concentrate and 50% propiconazole emulsifiable concentrate are used as reference objects in the same way, and the control effects after 72 hours of drug treatment are 58.31% and 50.05%, respectively. It can be clearly seen that the mixture The control effect of the preparation is 1.5-2 times higher than that of the two single doses.

Abstract

The invention discloses a compound fungicide composition containing tridemorpholine as a main component and its application. The compound fungicide composition is composed of component A and component B, wherein component A is tridemorpholine, and component B is any of difenoconazole, propiconazole, tebuconazole and myclobutanil. One, wherein component B also includes auxiliary materials, and the mass ratio of component A:component B is 1-40 parts:99-60 parts to form a compound composition. For the application of the composition, the above-mentioned component A and component B are weighed and mixed according to the mass ratio, and filled into 100 parts with water or fillers, which can be made into different application dosage forms, and the dosage forms include: water emulsion, microemulsion, Water-dispersible granules, wettable powders, suspending agents, emulsifiable concentrates, simple formula, low cost, easy to use, less drug residues on crops, production in line with environmental protection requirements, suitable for prevention and treatment of vegetables, wheat powdery mildew and banana leaf spot, mixed The control effect of the preparation is 2-3 times higher than that of the two single doses.

Description

technical field [0001] The invention relates to a pesticide fungicide composition, in particular to a compound fungicide composition containing trimorpholine as a main component and its application. Background technique [0002] Tridemorph, a single species, is a broad-spectrum systemic fungicide with protective and therapeutic effects, which can be absorbed by roots, stems, and leaves of plants, and is effective against various diseases caused by basidiomycetes, ascomycetes, and half-knowledge fungi. Effective against plant diseases, mainly inhibiting the biosynthesis of ergosterol in pathogenic bacteria. [0003] Difenoconazole, a single species, has protective, therapeutic and systemic activities, is a sterol demethylation inhibitor, inhibits the biosynthesis of cell wall sterols, and prevents the growth of fungi. Wide spectrum of sterilization, foliar treatment or seed treatment can improve crop yield and ensure quality. [0004] The single-variety propiconazole is a s...
