[0025] Biological Assay Example 1: Indoor Toxicity Determination of Fluquinazole and Disenlian Compound against Pear Scab

[0026] Test object: Pear scab fungus collected from the field

[0027] Test method: spore germination method. The pear scab was isolated from the lesion of fresh fruit collected from the field, and the pathogen was continuously cultured on PDA medium in an incubator at 25°C for three times for purification, and then inoculated on PDA medium to cultivate spores. Wash the cultured pear scab spores with water and prepare 4×10 5 spores / ml suspension. Dilute the test agent to the corresponding concentration, and mix it with the spore suspension of pear scab 2 mL plus 2 mL, and use 2 mL of sterile water plus 2 mL of the spore suspension as the blank control. Place them in a 24°C incubator for culture, check the spore germination rate after 15 hours, and calculate the relative inhibition rate of spore germination. For each treatment, 10 visual fields were ra...

[0038] Bioassay Example 2: Indoor Toxicity Determination of Fluquinazole and Propineb Compound to Tomato Early Blight

[0039] Test object: Tomato early blight fungus collected from the field

[0040] Test method: mycelial growth rate method. The tomato early blight bacteria was cultivated with PDA medium, and when the colony was just full of the culture dish, a hole was punched from the edge with a puncher with an inner diameter of 7 mm, and the resulting mycelium block was used as an inoculum. Take 5 mL of the prepared drug solution and mix them with quantitative 75 mL of sterilized medium to make 4 drug-containing plates, and use the same amount of sterile water mixed with the medium as a control. The mycelium block was placed upside down and placed in the center of the plate, and cultured in a 28°C incubator. After 7 days, the colony diameter was measured by the cross method, and the net mycelial growth and mycelial growth inhibition rate of each treatment were calculate...

[0048] Bioassay example 3: Indoor toxicity test of fluquinazole and mancozeb compound against wheat powdery mildew

[0049] Test object: Wheat powdery mildew bacteria collected from the field

[0050] Test method: potted plant method. Select wheat seedlings at the three-to-four-leaf stage with consistent growth vigor, and use three pots of wheat seedlings for each treatment. Wheat powdery mildew diseased leaves collected from the field were evenly shaken off the conidia above the wheat seedlings for inoculation, and treated with chemicals 24 hours later. See Table 3 for the test chemicals. Spray with a Potter spray tower at a pressure of 50PSI, about 5mL per treatment. Five concentration gradients were set for each agent, and the same amount of water sprayed was used as the blank control. After spraying, the wheat seedlings were put into the greenhouse for cultivation. After 7 days, the leaves of the whole plant were surveyed according to the incidence classification stand...

Abstract

The invention relates to a pesticide composition containing fluquinconazole. An effective component is a compound composition of fluquinconazole and any metiram germicide, wherein the mass proportion of the two effective components is 40:1-1:80, preferably 10:1-1:10, and the balance is an allowed and acceptable auxiliary component in pesticide. The metiram germicide is selected from zineb, maneb, ambam, mancozeb, propineb, thioneb, and the like. After being compounded with any metiram germicide according to a certain proportion, the fluquinconazole has obvious synergy effect and can be used for preventing and controlling diseases of various plants, such as vegetables, fruit trees, grain, and the like.

Description

technical field [0001] The invention relates to a pesticide composition, especially a compound composition containing fluquinazole. Background technique [0002] In the actual process of agricultural production, chemical control is the main effective means of disease control. However, in recent years, due to single drug use and other unscientific drug use methods, many pathogenic bacteria such as powdery mildew and Botrytis cinerea have developed resistance to the currently used pesticides, which has become a major problem in chemical control. Due to the resistance of the bacteria, the frequent application of pesticides by farmers has increased the burden and environmental pollution. However, if some high-efficiency agents are overused for a long time, they will also face the risk of drug resistance. In addition, due to the high price of newly developed new agents, it is difficult to be widely used in the market. Therefore, it is particularly important to find a fungicidal...
