preparation Embodiment

[0043] For uniformity, the auxiliaries used in the following preparation examples all use abbreviations or commodity codes.

[0044] 1. Preparation of suspending agent

[0045] Mix the surfactant, antifreeze, thickener, surfactant, and water, mix evenly by high-speed shearing, add isolongifolenone oxime lactam, triconazole in turn, and grind the balls in the ball mill for 2~ 3 hours, made the suspension concentrate of bactericide of the present invention.

[0046]

[0047] 2. Preparation of wettable powder

[0048] The isolongifolenone oxime lactam, triadol, wetting and dispersing agent, white carbon black, and fillers 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.

Embodiment 1

[0069] 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". In this test, the zone of inhibition method was used. On the aseptic operating table, pour the NA medium into the NA plate, and after drying, take 0.1ml of X. citri bacteria suspension and apply 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 cross method, and the average value of the diameter of...

Embodiment 2

[0075] The bacterial suspension concentration was 10 8 cfu mL -1 Add 0.5mL of pathogenic bacteria to each sterilized petri dish with a diameter of 9cm, then pour 15mL into gravy peptone medium cooled to 45°C, mix well, and solidify. At the bottom of the petri dish, mark the three corner positions of the regular triangle at an equidistant distance of 2.5 cm from the center, prevent the Oxford cup (10 mm in height, 6 mm in inner diameter), drop the same amount of different concentrations of the drug dilution solution, and store it under constant temperature and sterile conditions at 28 ° C. After culturing for 7 days, the diameter of the inhibition zone was measured, and the average value of the diameter of the inhibition zone and the inhibition rate were calculated. Use DPS data processing software for statistical analysis, and calculate the EC of each drug 50 , and then calculate the co-toxicity coefficient (CTC) according to Sun Yunpei's method.

[0076] The results of the...

Abstract

The invention discloses a compounded composition containing isolongifolenoneoximelactam and flutriafol as well as a preparation containing the isolongifolenoneoximelactam and the flutriafol. The compounded composition is composed of the isolongifolenoneoximelactam and the flutriafol, wherein the weight ratio of the isolongifolenoneoximelactam to the flutriafol is (20-1):(1-40); and the compoundedcomposition accounts for 0.1%-90% of the weight of the bactericide. The compounded composition provided by the invention can effectively prevent and control various bacterial diseases such as citrus canker diseases and cucumber bacterial angular leaf spot diseases, and can also prevent and control fungal diseases such as grape plasmopara viticola; and the compounded composition has obvious synergistic effects, the prevention effects are high, the use amount of pesticides is reduced, the prevent and control costs are reduced, and the drug resistance is delayed.

Description

technical field [0001] The invention relates to the technical field of pesticides, in particular to a compound composition and a bactericide containing isofenone oxime lactam and triconazole. 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 more and mo...
