Embodiment 6

[0193] Indoor Toxicity Measurement Example Six: Prevention and Treatment of Citrus Canker

[0194] Test method: 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...

[0230] Example 3 of Field Drug Effects: Controlling Peanut Underground Pests

[0231] The test was carried out with reference to the relevant content in the "Guidelines for Field Efficacy Tests of Pesticides II (GB / T 17980.72-2004)".

[0232] Test method: Mix seeds and apply pesticides when sowing, set up 6 plots, each plot is 66.7m 2 , repeating 4 times, a total of 24 cells are set up, and guard lines are set at the edge of the cells.

[0233] Investigation method: (1) Investigation of damage to peanut plants: Before harvesting, take samples at 5 points in the shape of a "Z" in each plot, each sample point is 1m long, check the total number of plants and the number of damaged plants in the sampling point, and calculate the control effect of the damaged plants .

[0234] (2) Investigation of insect population density: Before harvesting, excavate the soil and take samples for investigation, and take samples at 5 points in the shape of "Z" in each plot, investigate the number ...

Abstract

The invention discloses a methylsulfonylconazole-containing insecticidal and bactericidal composition and a preparation thereof. The insecticidal and bactericidal composition contains methylsulfonylconazole and an insecticidal compound II, wherein the insecticidal compound II is any one of chlorpyrifos, diazinon and carbosulfan; and the chemical name of methylsulfonylconazole is 2-(para-fluorophenyl)-5-methylsulfonyl-1,3,4-oxadiazole. The insecticidal and bactericidal composition and preparation thereof have obvious synergism relative to single dosage; and when the insecticidal and bactericidal composition and preparation are used for preventing and controlling crop pests and diseases, the prevention and control effect is improved, the dosage of pesticide is reduced, the cost is lowered, the lasting period is long, the pesticide using times is reduced, and environmental protection is facilitated.

Description

technical field [0001] The invention belongs to the technical field of pesticides, and in particular relates to an insecticidal and fungicidal composition and preparation containing mesycloconazole. Background technique [0002] The problem of resistance to agricultural diseases 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. Bacterial diseases, in particular, have a high degree of resistance and rapid development of resistance; at the same time, with the adjustment of planting structure, underground pests such as mole crickets, grubs, needleworms, and cutworms are currently more serious, and these pests can also carry pathogenic bacteria. . At present, the better pesticides for controlling underground pests are chlorpyrifos, diazinon, and carbosulf...
