specific Embodiment approach

[0038] The invention is illustrated by the following examples, which do not limit the scope of the invention. The original drug of isofenoneoxime lactam 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 isolongifolenone lactam (abbreviated as isolongifolenone lactam in the following table); the active component (B) is diazophos.

[0039] 1. Preparation of wettable powder

[0040] The isolongifolenone oxime lactam, methadone, wetting agent, dispersant, and filler are uniformly mixed, pulverized by a jet mill, and stirred for 30 minutes to obtain the wettable powder of the fungicide of the present invention.

[0042]

[0043] 2. Preparation of water dispersible granules

[0044]Mix isolongifolenone oxime lactam, pentadophos, wetting agent, dispersant, disintegrating agent and filler evenly, pulverize through jet mill, stir for 30 minutes,...

[0079] Controlling Citrus Canker

[0080] 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".

[0081] 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 synergistic effects. The compound composition comprises active components of isolongifolenone oxime lactam and Dufulin, wherein the weight ratio of isolongifolenone oxime lactam to Dufulin is (20-1): (1-40); and the total weight of isolongifolenone oxime lactam and Dufulin accounts for 0.1% to 90% of the total weight of the compound composition.According to the invention, an auxiliary agent and an excipient are added into the active components, so the compound composition can be prepared into the following dosage forms: a wettable powder, awater dispersible granule, a seed coating agent, a seed dressing agent, a suspension concentrate, an emulsion in water, a granule or a sustained-release agent. The bactericide composition provided bythe invention has excellent eradication, treatment and protection activities, can be applied to a variety of crops like rice, peanuts, vegetables and fruit trees, and prevents and treats various bacterial and fungal diseases like rice baeterial 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 and preparation containing an isolongifolenone oxime lactam and hexafluorophos. Background technique [0002] The problem of resistance to agricultural pests is a global problem. With the continuation of chemical disease control, the increase in the use of pesticides, and the unscientific use of pesticides, the resistance of pathogens is becoming more and more serious, and the types of pathogens that are resistant are increasing. Especially for bacterial diseases, the degree of resistance is high and the speed of resistance development is fast. [0003] As people's awareness of environmental protection and social sustainable development continues to increase, especially in the 21st century, finding and excavating new natural medicines from plant resources for use in medicine or agriculture has become an important research topic around the world. It is ...
