Synergistic compound for preventing and treating strawberry gray mold and application thereof

Abstract

The invention relates to the field of pesticides, in particular to a synergistic compound for preventing and treating strawberry gray mold and application thereof. The compound is prepared from a biological fungicide Serenadesoil, phenazine-1-formamide, alternaria tenuissima protein, seaweed essence, kasugamycin and magnolol, wherein the mass ratio of the biological bactericide Serenadesoil to the phenazine-1-formamide to the alternaria tenuissima protein to the seaweed extract to the kasugamycin to the magnolol is (3-6): (1-9): (0.5-2.5): (1-9): (1-3): (5-10). The synergistic compound provided by the invention can be used for synergistic prevention and treatment of strawberry gray mold, delays the drug resistance of germs, and prolongs the lasting period.

Description

technical field [0001] The invention relates to the field of pesticides, in particular to a synergistic compound for preventing and treating gray mold of strawberry and its application. Background technique [0002] Strawberry Botrytis is a disease of strawberries caused by Botrytis cinerea infection. It mainly harms strawberry flower organs, fruits, petioles and leaves, and different parts show different symptoms. Symptoms of Leaf Damage In the early stage of the disease, the old leaves form "V"-shaped yellow-brown lesions, and as the disease worsens, the leaves scorch and die. In order to achieve effective control of strawberry gray mold, many chemical agents are used in production, but the long-term use of chemical agents in large quantities not only pollutes the environment, but also easily causes the bacteria to develop drug resistance. At present, the strawberry gray mold in many areas has developed resistance to fludioxonil, boscalid, procymidone, carbendazim, dieth...

In order to achieve effective control of strawberry gray mold, many chemical agents are used in production, but the long-term use of chemical agents in large quantities not only pollutes the environment, but also easily causes the bacteria to develop drug resistance

At present, the strawberry gray mold in many areas has developed resistance to fludioxonil, boscalid, procymidone, carbendazim, diethofencarb and other agents, which has greatly increased the prevention and control of strawberry gray mold. Less difficulty
