experiment example 1

[0023] Test object: Cucumber downy mildew

[0024] The pot cutting method was used for determination, and the cucumber seedlings were used when they reached the four-leaf stage. There are 10 groups (one ratio is one group) for chemical treatment, each group has 3 replicates, each replicate has 4 pots, and clear water is the control group. Prepare and dilute 100mL of medicaments in different proportions, and use crop spray foliar spray to treat cucumber seedlings respectively. After 24 hours of chemical treatment, inoculate the activated bacteria (spray inoculation method, spore concentration of 2×10 6 per mL, just spray until the leaf surface is wet), and the disease condition investigation was carried out 8 days after inoculation.

[0025] The co-toxicity coefficient (CTC) method was used to determine the joint action mode. The formula for calculating the co-toxicity coefficient is as follows:

[0026] Measured Toxicity Index (ATI) = (standard drug EC 50 / Test agent EC ...

[0033] Experimental Example 2 Subject: Tomato Blight

[0034] The experimental method also adopts the potted method, and the specific method steps refer to Experiment 1. The results of indoor toxicity test are shown in Table 2:

[0035]

[0036] The test results showed that fendol and pyraclostrobin had a synergistic effect on tomato blight within a certain ratio range, and when the ratio was between 1:15 and 15:1, the co-toxicity coefficients were all above 120.0, which was excellent. The matching ratio is 1:5.

Abstract

The invention discloses a sterilization composition containing folpet and isopyrazam and application thereof. The sterilization composition uses folpet and isopyrazam as major active ingredients, wherein the mass ratio of the folpet to the isopyrazam is (1 to 50):(50 to 1). The sterilization composition can be applied to the prevention and treatment of cereal crop and vegetable and fruit tree diseases, has high synergistic interaction effects, overcomes and delays the pathogenic bacterium drug resistance, and has the advantages that the sterilization speed is high; the effect duration period is longer; the application cost is reduced; the prevention and treatment effects are obviously better than those of other single agents when being used. The sterilization composition can be used for preventing and treating fungus diseases on the crops, and can be particularly used for preventing and treating fruit and vegetable downy mildew and epidemic diseases; the prevention and treatment effects are better than that of a single agent.

Description

technical field [0001] The invention relates to the field of agricultural fungicides, in particular to a fungicide composition containing folpet and pyraclostrobin and an application thereof. It is mainly used to control downy mildew and blight of melons and fruits, especially cucumber downy mildew, grape downy mildew, tomato blight, potato blight, and watermelon blight. Background technique [0002] Folpet, also known as Falton, Folpet, CAS registration number: 133-07-3, its chemical name is N-(trichloromethylthio)phthalimide or N-(trichloro Methylthio) phthalimide, its molecular formula C 9 h 4 Cl 3 NO 2 S, the molecular weight is 296.56. It is a broad-spectrum protective fungicide, which mainly prevents various diseases such as rice sheath blight, rice blast, tobacco anthracnose, peanut leaf spot, rape sclerotinia, potato late blight, and melon frost in grain and oil crops, vegetables, and fruit trees. Mildew, safe for crops. [0003] Isopyrazam is a succinate dehy...
