Abstract

The invention belongs to the technical field of pesticide and relates to a pesticide for preventing and treating fruit diseases such as strawberry anthracnose, powdery mildew and root rot disease, grape white rot and powdery mildew, pear scab and the like. The pesticide comprises the active compositions of ethylicin and pyrachostrobin with the weight ratio of 1-50:1-20, and preferably 10-40:1-15. The invention has the advantages that firstly, the drug resistance caused by long-term use of single preparation is avoided, and the effective time of pesticide is prolonged; secondly, the combination of the ethylicin and the pyrachostrobin has a better synergistic effect, and the application amount and the cost are reduced; thirdly, the pesticide improves the treating effect, widens the anti-fungal spectrum, and has long effective duration and good effect on preventing and treating a plurality of diseases; and fourthly, the pesticide has low toxicity and non-pollution and is safe for environment.

Description

technical field [0001] The invention belongs to the technical field of pesticides, and relates to an insecticide for preventing and controlling fruit tree diseases which can prevent and control strawberry anthracnose, powdery mildew and root rot, grape white rot, powdery mildew, pear scab and other diseases. Background technique [0002] Ethyl allicin, other Chinese name: antibacterial agent 402, English common name: ethylicin, chemical name: ethyl ethyl thiosulfonate, molecular formula: C4H10O2S2. It is a plant-derived biomimetic pesticide, which is the ethyl homologue of allicin, an extract of edible garlic. Its bactericidal mechanism is that the (S-S=O=O) group in its molecular structure reacts with the substance containing -SH group in the cell molecule, thereby inhibiting the normal metabolism of the cell; it has a stimulating effect on plant growth, and the treated The seeds emerge quickly and the seedlings grow robustly. It can be widely used in crops such as grain, ...
