Problems solved by technology

In some places where the disease occurs seriously, common fungicides such as chlorothalonil, thiophanate-methyl, thiram, etc. alone have no effect
Due to the large-scale application of triadimefon, etc., it has also caused serious resistance and is prone to phytotoxicity.
[0005] There is no relevant report on the compound product of tebuconazole and iprodione

example 1

[0034] Example 1: 70% tebuconazole iprodione wettable powder

[0035] Tebuconazole 30g, iprodione 40g, polycarboxylate 5g, sodium methylene bisbenzene sulfonate 3g, sodium dodecylbenzene sulfonate 5g, white carbon black 10g, the remainder of kaolin, placed in a mixer and stirred , 70% tebuconazole · iprodione wettable powder can be made by jet crushing to 500 mesh.

example 2

[0036] Example 2: 60% tebuconazole iprodione water dispersible granules

[0037] 25g of tebuconazole, 35g of iprodione, 4g of sodium lignosulfonate, 8g of sodium lauryl sulfate, 3g of ammonium sulfate, 2g of starch, and the remainder of kaolin, mix the ingredients evenly, and pulverize with an ultrafine jet mill. After kneading, it is added to a fluidized bed granulation dryer for granulation, drying, sieving, and after sampling and analysis, it can be made into 50% tebuconazole·iprodione water-dispersible granules.

example 3

[0038] Example 3: 50% Tebuconazole · Iprodione Suspension Concentrate

[0039]20g tebuconazole, 30g iprodione, 3g carboxymethylcellulose, 4g glycerol, 0.1g organosilicone, 0.1g xanthan gum, 0.8g magnesium aluminum silicate, 1g white carbon black, and the rest of water. The rest of the components in the above formula except the active ingredients are uniformly mixed through high-speed shearing, the active ingredients are added, and ball milled in a ball mill for 2 to 3 hours, so that the particle size is all below 5 μm, and 50% tebuconazole is obtained. ·Iprodione suspension

Abstract

The invention relates to a sterilizing composition which is a suspending agent comprising active components of Tebuconazole and iprodione, wherein the weight percentage of the active components of the Tebuconazole and the iprodione is 1-60:1-60. The invention is used for preventing and curing general diseases on crops and fruit trees, has extremely remarkable effects of preventing and curing rice sheath blight disease, sigatoka, apple alternaria leaf spot and has obvious effect higher than single agents. The sterilizing agent can generate higher synergistic effect, overcomes and retards the disease drug resistance, broadens the preventing and curing spectrum, reduces the dosage and the drug treatment times, decreases the cost and lightens the toxicity.

Description

Technical field: [0001] The invention belongs to the technical field of pesticides, and relates to a compound fungicide containing tebuconazole and iprodione, which is used for the prevention and control of diseases on grains and fruit trees. technical background: [0002] Tebuconazole, a triazole fungicide, is a systemic fungicide with protective and therapeutic effects. It is an episterol biosynthesis inhibitor, which can be quickly absorbed by the growing part of the plant and mainly transferred to the top. . Not only has bactericidal activity, but also can promote the growth of crops, so that the root system is developed, the leaves are dark green, the plants are strong, and the effective tillers increase, thereby increasing the yield. Tebuconazole has strong systemic property, high drug efficacy, safety and long-lasting effect on crops, and it will be the development direction in the field of fungicides in the future. It can be used to prevent and control cereal crop ...
