specific Embodiment approach

[0060] 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 mesylconazole; the active component (B) is chlorobromoisocyanuric acid.

[0061] Formulation preparation embodiment:

[0062] 1. Preparation of wettable powder

[0063] Mix mesycloconazole, chlorobromoisocyanuric acid, dispersant, wetting agent, and solid carrier evenly, pulverize in a jet mill, and stir for 30 minutes to obtain the wettable powder of the fungicide of the present invention.

[0064]

[0065] 2. Preparation of dry suspension

[0066] Mix the surfactant and water, mix evenly by high-speed shearing, add mesycloconazole and solid carrier and grind the ball in a ball mill for 2 to 3 hours, then dry and pulverize, and finally add ultrafinely p...

Embodiment 2

[0098] Pull out the test tube cotton plug near the alcohol lamp, pour 10ml of sterile water, and gently scrape the bacteria on the slope with a sterile inoculation needle to suspend the spores, then pour the spore suspension Put it into a sterilized triangular flask with several glass balls in advance, shake it for 5 minutes, filter the bacterial solution with sterilized gauze, put it in another sterilized triangular flask, and then make the required bacterial solution.

[0099] Melt the beef extract peptone agar medium, and when cooled to 45°C-50°C, quickly pour it into sterilized petri dishes together with 0.2ml of bacterial suspension under aseptic conditions, 15ml of medium in each dish, shake well and cool down solidification. Use a sterilized hole puncher (aperture 4mm) to make a hole, drop 1ml of the drug solution into the round hole, place it in a 28°C incubator for 2 days, and measure the two diameters of the inhibition zone with a vernier caliper according to the cro...

Abstract

The invention provides a compound composition containing 2-(p-fluorophenyl)-5-methanesulfonyl-1,3,4-oxadiazole and chlorobromoisocyanuric acid and a preparation. The compound composition comprises active components, namely 2-(p-fluorophenyl)-5-methanesulfonyl-1,3,4-oxadiazole and chlorobromoisocyanuric acid, wherein the weight ratio of 2-(p-fluorophenyl)-5-methanesulfonyl-1,3,4-oxadiazole to chlorobromoisocyanuric acid is (20-1):(1-40), and 2-(p-fluorophenyl)-5-methanesulfonyl-1,3,4-oxadiazole and chlorobromoisocyanuric acid account for 0.1-90% of the total weight of the compound composition. The compound composition can be prepared into dosage forms such as a seed coating, a seed dressing agent, wettable powder, water dispersible granules, a dry suspending agent or granules. The compound composition provided by the invention can be used for preventing and controlling bacterial diseases, viral diseases and fungous diseases on crops, so that the effects of preventing diseases, delaying disease spreading, enhancing the plant resistance and ensuring the yields of the crops and the like are achieved.

Description

technical field [0001] The invention relates to the technical field of pesticides, in particular to a compound composition containing mesycloconazole and chlorobromoisocyanuric acid and its preparation and application. Background technique [0002] In recent years, with major adjustments in crop planting patterns, the intensification, scale, and specialization of agricultural production have become more and more obvious. The same or similar crops have been planted consecutively and year after year, resulting in an increase in the occurrence of various diseases and insect pests year by year. the trend of. In particular, some systemic infections and destructive diseases, such as bacterial wilt of melons and solanaceous vegetables, viral diseases and fusarium wilt of various crops, etc., the area of ​​occurrence is increasing year by year, and the degree of damage is constantly increasing. At the same time, due to the lack of effective chemical control agents, once bacterial d...
