[0043] (1) Biological detection of synergistic effect
[0044] Adopt Sun Yunpei (SunY-P) method, by calculating co-toxicity coefficient (co-toxicitycoefficient, CTC), evaluate the mixing effect of two kinds of active ingredients in the fungicide composition of the present invention, specifically as follows:
[0045] Evaluation criteria: when CTC ≥ 120, it shows a synergistic effect; when CTC ≤ 80, it shows an antagonistic effect; 80 < CTC < 120, it shows an additive effect.
[0046] Calculation formula:
[0047] Co-toxicity coefficient (CTC) = [mixture actual toxicity index (ATI) / mixture theoretical toxicity index (TTI)] × 100
[0048] Mixture Actual Toxicity Index (ATI) = (LC of standard drug 50 / Mixed LC 50 )×100
[0049] Mixture theoretical toxicity index (TTI) = TI of agent A × content of A in the active ingredient of the mixture + TI of agent B × content of B in the active ingredient of the mixture
[0050] Toxicity index (TI) = (LC of standard drug 50 / LC of test...

Abstract
The invention discloses a bactericide, which contains pyraclostrobin as the active ingredient. Specifically, the active ingredient also contains berberine, and pyraclostrobin and berberine are in a weight ratio of 1:0.01-90. The invention also provides application of the bactericide in control of crop diseases caused by fungi or bacteria. Compared with single-component pyraclostrobin or berberine, the bactericide provided by the invention has unexpected synergistic effect, can significantly improve the control effect, and is safe to target crops. Due to the presence of non-single active ingredient, drug resistance is difficult to produce. The bactericide can control a variety of diseases occurred together, has a broad control spectrum, and reduces the dosage of pesticides, saves cost, avoids or delays the generation of drug resistance, and alleviates pollution to the environment.
Description
technical field [0001] The invention relates to the field of plant protection, more specifically to a fungicide containing pyraclostrobin and its application in preventing and controlling crop diseases caused by fungi or pathogens. Background technique [0002] In the actual process of agricultural production, there are often problems of mixed occurrence of different types of diseases, such as powdery mildew, anthracnose, downy mildew, white rot, black pox, leaf mold, gray mold, early blight, late blight, Blight, bacterial wilt, scab, shaft rot, leaf spot are diseases that often exist simultaneously or in succession, for example, on vegetables, fruit trees, tea trees, flowers and lawns and other commercial crops. [0003] For the above common diseases, different fungicides are usually used for prevention and control. For example, powdery mildew is generally controlled by carbendazim, triadimefon or prochloraz, anthracnose is generally controlled by fluazinam, and downy milde...
