Problems solved by technology

[0002] Any new pesticide ingredient, due to long-term single use, is prone to drug resistance, resulting in a decline in its biological activity, which is an insurmountable problem in the process of pesticide development
Similarly, the long-term use of a single dose of triazolol will easily cause the disease to develop drug resistance, resulting in increased dosage, reduced control effect, and shortened duration, which is not conducive to sustainable development of the environment.

specific Embodiment approach

[0055] The invention is illustrated by the following examples, which do not limit the scope of the invention. The original drug of mesycloconazole used in the present invention is provided by Guizhou University, and other original drugs and preparations used are commercially available. Wherein the active component (A) is mesyconazole (abbreviated as mesylate in the following tables); the active component (B) is triconazole.

[0056] 1. Preparation of wettable powder

[0057] Mix mesyconazole, triconazole, wetting agent, dispersant, and filler evenly, pulverize through a jet mill, and stir for 30 minutes to obtain the wettable powder of the fungicide of the present invention.

[0058]

[0059] 2. Preparation of water dispersible granules

[0060] Mix mesyconazole, triconazole, wetting agent, dispersant, disintegrating agent, and filler evenly, pulverize through a jet mill, stir for 30 minutes, knead with water, and then add it to a fluidized bed granulation dryer for Gran...

[0096] Controlling Citrus Canker

[0097] The test refers to "Pesticide Bioassay Technology" (Edited by Chen Nianchun, published by Beijing Agricultural University Press) and "Pesticide Indoor Bioassay Test Guidelines NY / T1156.2-2006".

[0098] In this test, the inhibition zone method is used. On the aseptic operating table, pour the NA medium onto the NA plate, and after drying, take 0.1ml of the suspension of X. citrus bacteria and spread it evenly on the NA plate with a coating stick. . After drying, punch a hole in the center of the plate with a hole puncher with a diameter of 7 mm, and then take 100 μl of the drug solution into the small hole. 5 replicates for each concentration. The treatment of adding sterile water to the small well was used as the blank control. After treatment, place them in an incubator at 28±0.5°C for sterile cultivation, and take them out after 2 days. The diameter of the inhibition zone (in millimeters) of each treatment was measured by the cr...

Abstract

The invention provides a compound composition with a synergistic effect. The compound composition comprises active components, namely 2-(p-fluorophenyl)-5-methanesulfonyl-1,3,4-oxadiazole and flutriafol, wherein the weight ratio of 2-(p-fluorophenyl)-5-methanesulfonyl-1,3,4-oxadiazole to flutriafol is (20-1):(1-40), and 2-(p-fluorophenyl)-5-methanesulfonyl-1,3,4-oxadiazole and flutriafol account for 0.1-90% of the total weight of the compound composition. After a prompter and an excipient are added, the compound composition can be prepared into dosage forms such as wettable powder, water dispersible granules, a seed coating, a seed dressing agent, a suspending agent, an emulsion in water, granules or a slow-release agent. The bactericide composition provided by the invention simultaneously has excellent removing, treating and protecting activities and can be used on various crops such as rice, peanuts, vegetables and fruit trees to prevent and control various bacterial diseases and fungous diseases such as rice bacterial leaf streak, citrus canker, tomato bacterial wilt and phoma arachnidicola.

Description

technical field [0001] The invention relates to the technical field of pesticides, in particular to a compound composition containing mesyconazole and triconazole and a fungicide. Background technique [0002] Any new pesticide ingredient, due to long-term single use, is prone to drug resistance, resulting in a decrease in its biological activity, which is an insurmountable problem in the development of pesticides. Similarly, the long-term use of a single dose of triadol will easily cause the disease to develop drug resistance, resulting in increased dosage, reduced control effect, and shortened duration, which is not conducive to sustainable development of the environment. The compounding of pesticide active ingredients with different action mechanisms is a common method to improve the control effect and delay the development of disease resistance. And according to the effect in the actual production and application, it is judged whether the compound is a synergistic effec...
