Abstract

The invention discloses a composite fungicide composition containing a Psoralea corylifolia seed extract and prothioconazole, a fungicide and application. The mass ratio of the Psoralea corylifolia seed extract to the prothioconazole is 1:(99-200). The invention further discloses the application of the fungicide in prevention and treatment of peach brown rot, grape anthracnose and strawberry graymold on fruit trees. After the seed extract and the prothioconazole are compounded according to a certain ratio, strong synergistic effects are achieved, and field test results show that the highest control effect on peach brown rot, grape anthracnose and strawberry gray mold can reach 100% and is obviously superior to the control effect of the seed extract and a single preparation of the prothioconazole, the chemical cost is saved, the chemical resistance is delayed, and the fungicide composition has a good application prospect.

Description

technical field [0001] The invention belongs to the field of agricultural fungicides, in particular to a compound fungicide composition containing psoraleae seed extract and prothioconazole, a fungicide and its application. Background technique [0002] Peach, grape and strawberry are the main fruits in our country, and the disease damages the leaves, flowers and fruits of fruit trees, which directly or indirectly affect the yield and quality of fruit trees. Common diseases of fruit trees include brown rot, anthracnose and gray mold. With the wide application of long-term single-acting fungicides in fruit trees, pathogenic bacteria will develop resistance to fungicides, and the diseases that are difficult to prevent are seriously harmful. Due to the long-term use of carbendazim and diethofencarb to prevent brown rot, anthracnose and gray mold, fruit tree disease resistance is common. Compounds with excellent control effects in the past may become a component of the compound...
