Embodiment 1

[0050] Virulence Determination Example 1 Indoor Toxicity Determination Test on Potato Late Blight

[0051] Test object: Potato infestans ( Phytophthora infestans (Mont.) de Bary )

[0052] Test method: refer to the standard method of bioassay NY / T 1156.2-2006, using the medium method containing medicine: take 3mL of the medicine solution with a series concentration of each single agent and mixed agent, add it to 27mL PDA medium cooled to 45°C, and prepare Prepare the drug-containing medium plate at the desired final concentration. Then, a 6 mm-diameter mycelium block was prepared from the edge of the P. infestans colony cultured for 7 days, and moved to each series of drug-containing medium with the mycelium facing down, and each treatment was repeated 4 times. After the treatment, culture in a constant temperature biochemical incubator at 25°C, measure the colony diameter after 4 days, and calculate the growth inhibition rate. Through the linear regression analysis betwee...

[0061] Toxicity Determination Example 2 Indoor Toxicity Determination Test on Tobacco Black Leg Disease

[0062] Subject: Tobacco black shank (Phytophtora parasitica var. nicotianae Tucker)

[0063] Test method: refer to the standard method of bioassay NY / T 1156.2-2006, using the medium method containing medicine: take 3mL of the medicine solution with a series concentration of each single agent and mixed agent, add it to 27mL PDA medium cooled to 45°C, and prepare Prepare the drug-containing medium plate at the desired final concentration. Then, a 6 mm-diameter mycelial block was prepared from the edge of the tobacco black shank colony cultured for 7 days, and moved to each series of drug-containing medium, with the mycelium facing down, and each treatment was repeated 4 times. After the treatment, culture in a constant temperature biochemical incubator at 25°C, measure the colony diameter after 4 days, and calculate the growth inhibition rate. Through the linear regressi...

Embodiment 3

[0072] Toxicity Determination Example 3 Indoor Toxicity Determination Test to Chinese Cabbage Clubroot

[0073] Test object: clubroot of Chinese cabbage

[0074] Test method: refer to the standard method of bioassay NY / T 1156.1-2006, adopt the test of inhibiting the germination of pathogenic fungus spores (concave slide method): the spore suspension is prepared, and the cultured Chinese cabbage clubroot spores are cultured with deionized water from Elute on the base, filter, centrifuge for 5 minutes, pour off the supernatant, add deionized water, and centrifuge again. Finally, the spores were resuspended to 1 × 10 in deionized water. 5 ~1×10 7 spores and added 0.5% glucose solution. Use a pipette to prepare medicaments of different concentrations from low concentration to high concentration, draw 0.5ml of the medicinal solution at a time and add them to small test tubes, and then draw 0.5ml of the prepared spore suspension to make the medicinal solution and spore suspension...

Abstract

The invention provides an antifungal composition containing misulrom and fluzinm and an application thereof. The composition comprises the effective ingredient misulrom and the effective ingredient fluzinm, the mass ratio of the misulrom to the fluzinm is 100:1 to 1:100, and the total mass percent of the effective ingredients in the antifungal composition is 5% to 85%. The antifungal composition can be prepared into wettable powders, water dispersible granules, suspending agents, suspoemulsions, microemulsions, emulsions in water, microcapsule suspensions and microcapsule suspending-suspensions. The antifungal composition is used for controlling disease on vegetables, fruit trees and tobaccos. The antifungal composition has the remarkable synergistic interaction effect, the usage quantity of pesticides can be reduced, the control effect can be improved, and the antifungal composition is low in toxicity and residue, safe, environmentally friendly and safe when used for crops.

Description

technical field [0001] The invention belongs to the technical field of pesticides, and in particular relates to a fungicidal composition containing effective components indazole sulfastrobin and fluazinam and its application for preventing and controlling crop diseases. Background technique [0002] Fungi are the most important plant pathogens, and more than 70% of plant diseases are caused by fungi. Because of the complex pathogenic factors, it is very difficult to control them. In recent years, with the adjustment of rural planting structure, the planting area of ​​fruit trees and vegetables has been increasing, and the occurrence of many fungal diseases on fruit trees and vegetables has also increased, causing huge economic losses. [0003] Plant fungal blight is divided into early blight and late blight. Early blight is caused by higher fungi, belonging to the fungus Alternaria genus of the subphylum Deuteromycetes. The most common early blight is tomato, pepper, potato...
