Embodiment 1

[0025] Embodiment 1: Ringworm.

[0026] Made by conventional technology, according to the weight ratio of disenlian (unless otherwise specified, it refers to the weight percentage) 20%, with different weight ratios of 20% thiophanate-methyl, 10% carbendazim, and 25% myclobutanil , difenoconazole 15%, propiconazole 16%, tebuconazole 22%, polyoxin 30%, and benomyl 9%, respectively mixed with one kind, and then added a certain weight ratio of wetting Agents, diffusing agents and fillers are made into wettable powders. All formulas are diluted and sprayed by 1000-1500 times, and the field control effects are 90.8%, 89.7%, 91.2%, 90.4%, 90.9%, 92.0%, 88.7%, 89.1% after 72 hours of application; A single dose of thiophanate-based can be formulated into a wettable powder, or a single dose of 10% carbendazim can be formulated into a wettable powder, or a single dose of 25% myclobutanazole can be formulated into a wettable powder, or a single dose of 15% difenoconazole can be formulate...

Embodiment 2

[0027] Example 2: Anthrax.

[0028] Made by conventional technology, according to the weight ratio of disenlian (unless otherwise specified, all refer to weight percentage) 35%, and in different weight ratios 15% of thiophanate-methyl, 30% of carbendazim, and 10% of myclobutanil , difenoconazole 30%, propiconazole 34%, tebuconazole 38%, polyoxin 10%, and benomyl 30%, mix one or two or more of them respectively, and then add A wetting agent, surfactant, emulsifier, cosolvent, antifreeze, thickener, defoamer, and water in a certain weight ratio are used as the balance to make a suspending agent. All formulas are diluted and sprayed by 1500-2500 times, and the field control effects are 88.7%, 89.1%, 90.3%, 92.3%, 90.6%, 92.0%, 89.9%, 88.1%, 93.5% in 72 hours after spraying; Use 15% thiophanate-methyl as a single agent to prepare a suspension, or use 30% carbendazim as a single agent to prepare a suspension, or use 10% myclobutanazole as a single agent to prepare a suspension, or...

Abstract

The invention discloses a fungicide composition containing the active ingredient of disenlian. Bactericide composition comprises active ingredient component A and active ingredient component B to form; Wherein active ingredient component A is the active ingredient of Dysenlian, and active ingredient component B includes at least one following bactericide, and its bactericide is Thiophanate-methyl, carbendazim, myclobutanazole, difenoconazole, propiconazole, tebuconazole, hexaconazole, polyoxin or benomyl; active ingredient component A by mass ratio: The weight ratio of the active ingredient component B is 50:1-1:50. The feature of the present invention is that the binary bactericidal composition can prevent and control ring spot and anthracnose which are difficult to control in agriculture, and can also prevent and control diseases such as spotted leaf disease on fruit trees, and the control effects are 87.9%, 89.4%, and 90.5% respectively. %, 92.3%, 93.8%, 89.7%, 90.6%, 91.2%.

Description

technical field [0001] The pesticide fungicide composition that the present invention relates to, particularly relates to a kind of fungicide composition containing the active ingredient of Disenlian. technical background [0002] Most of the existing pesticide fungicides are composed of single-agent varieties and additives. This single-agent variety has the disadvantage of poor pest control effect. The disadvantages of single-agent varieties are described below: [0003] Thiophanate-methyl, carbendazim, and benomyl are three relatively common systemic fungicides, which belong to the benzimidazole class; their main mechanism of action is to interfere with the formation of the spindle in the mitosis of bacteria, thereby affecting the formation of bacterial mitosis. In recent years, the drug resistance of single-control diseases has been significantly enhanced, resulting in poor control effects. [0004] Myclobutanil, difenoconazole, propiconazole, tebuconazole, and hexacona...
