Embodiment 1

[0034] Control effect embodiment 1, the indoor virulence determination of control cucumber powdery mildew

[0035] The experimental method refers to the "People's Republic of China Agricultural Industry Standard NY / T1156.11-2008 Indoor Bioassay Test Guidelines for Pesticides and Fungicides Part 11: Potted Plant Method for Controlling Melon Powdery Mildew Test". First, set 5 different concentrations of the single agent and each mixed agent. Wash the fresh spores on the cucumber leaves covered with powdery mildew bacteria with pure water added with a small amount of surfactant, filter with double-layer gauze, and make a suspension with a spore concentration of 1*105 spores / ml for future use. For each treatment, 3 pots were repeated 4 times, and the treatment containing only solvent and surfactant but no active ingredient was set as a blank control. Inoculate with the spore suspension 24 hours before the chemical treatment, spray the liquid evenly on the leaf surface until it is...

Embodiment 2

[0050] Control effect embodiment 2, the indoor efficacy determination of control grape powdery mildew

[0051] Preparation of spore suspension of powdery mildew of grapevine

[0052] Collect fresh grape powdery mildew spores, and use sterile water to make a concentration of 2*10 5 1 / ml spore suspension, add 7.8 grams of glucose per 1000ml, and inoculate after 24 hours.

[0053] experimental method

[0054]The spores germinated on the glass slide, and the pre-prepared test drug solution was sprayed on the glass slide with a small throat sprayer, and the spraying of distilled water was used as a control. After drying, gently adhere the fresh spores on the diseased leaves to the side of the glass slide where the liquid is sprayed, and then place the glass slide in a petri dish lined with two absorbent filter papers. Put the bacterial water on the filter paper to make it fully absorb water, cover it, and place it in a 20-degree incubator to keep the filter paper moist. All trea...

Embodiment 3

[0062] Control effect embodiment 3, field experiment control grape powdery mildew

[0063] experiment method

[0064] The experiment was carried out in the grape planting area of ​​Shenyang City, Liaoning Province. Four points were investigated in each plot, and two plants were investigated in each point. The degree of disease was recorded by the classification method. The classification standards are as follows:

[0065] Level 0: no disease;

[0066] Grade 1: Lesion area accounts for less than 5% of the entire leaf area;

[0067] Grade 3: Lesions account for 6%-10% of the entire leaf area;

[0068] Grade 5: The lesion area accounts for 11%-20% of the entire leaf area;

[0069] Level 7: Lesions account for 21%-50% of the entire leaf area;

[0070] Grade 9: The lesion area accounts for more than 50% of the entire leaf area.

[0071] Survey time and frequency

[0072] There were 4 surveys in the test, the baseline survey before the drug, 14 days after the first drug, 14 da...

Abstract

The invention relates to the technical field of pesticide compounding, and discloses a fungicide composition containing benziothiazolinone and metrafenone. The fungicide composition comprises effective components of benziothiazolinone and metrafenone, wherein the mass ratio of benziothiazolinone to metrafenone is (1: 40) to (40: 1); and the total mass of the effective components accounts for 1% to 80% of the total mass of the whole preparation, with the balance being auxiliary components. The fungicide composition can be prepared into an emulsifiable concentrate, a microemulsion, an emulsion in water, a suspension concentrate, a dispersible oil suspension, wettable powder, a water dispersible granule, a seed-coating suspension, a seed-coating emulsion in water, seed-treating dispersible powder and a seed-treating dispersible granule. The fungicide composition provided by the invention has significant synergistic effects and is mainly used for preventing and treating powdery mildew of wheat, rice, cucumber, grape and apples.

Description

technical field [0001] The invention relates to the technical field of pesticide compounding, in particular to a fungicidal composition containing thiamethoxamin and metrafenone, which is mainly used for preventing and treating powdery mildew of wheat, rice, cucumber, grape and apple. [0002] technical background [0003] Thiemadone is a high-efficiency, low-toxicity, broad-spectrum fungicide, which can destroy the cell membrane protein and synthesis system of pathogenic bacteria, thereby inhibiting the reproduction of pathogenic bacteria, interfering with the metabolism of pathogenic bacterial cells, making them physiologically disordered, and leading to the death of pathogenic bacteria. The compound has good control effects on various crop diseases caused by bacteria and fungi, and is very safe to crops and the environment. [0004] Metrafenone, the chemical name is (3‐bromo‐6‐methoxy‐2‐methylphenyl)‐(2,3,4‐trimethoxy‐6‐methylphenyl)methanone, from BASF, Germany Benzophen...
