Problems solved by technology

Moreover, Botrytis cinerea, which causes strawberry gray mold, is prone to develop resistance, and is almost resistant to commonly used chemical fungicides.
Conventional chemical control measures are not only useless to solve the problem of field diseases, but also cause the phenomenon of excessive pesticide residues in strawberry fruit, which seriously restricts the development of strawberry industry
Through document retrieval, do not see a kind of environmental friendly strawberry botrytis control side public report identical with the present invention

Embodiment 1

[0023] A kind of environment-friendly strawberry gray mold control method, its steps are:

[0024] 1. The test site is located in Dongshan Farm, Dongxihu District, Wuhan City, Hubei Province. The strawberry variety for testing is 'Sweet Charlie', which was planted on September 15, 2016. From after planting to before flowering, use chemical pesticides for foliar spraying every 10 or 13 or 15 days, 3 or 4 times in a row. Control the incidence of diseases and insects on strawberry plants within 1%, reduce the number of diseases and insects, and lay the foundation for the later development of Botrytis cinerea. Chemical pesticides include: difenoconazole, captan, pyraclostrobin, and eugenol, and each pesticide is used once in sequence.

[0025] 2. From the beginning of budding to the full bloom period of the first batch of flowers: investigate the occurrence of diseases in strawberry greenhouses, and there is no powdery mildew in the greenhouses.

[0026] 3. Seven days after the ...

Abstract

The invention discloses an environmentally friendly strawberry grey mould prevention method. The environmentally friendly strawberry grey mould prevention method comprises the following steps: A, fromplanting to pre-blooming: spraying a chemical pesticide on leaves, controlling the base number of diseases and pests on a strawberry plant; B, from the appearance of a bud to the full-bloom period ofthe first batch of flowers: investigating the disease of a strawberry planting greenhouse, continuing to prevent the strawberry grey mould if no powdery mildew occurs in the greenhouse; C, after thefull-bloom period of the first batch of flowers: starting an air blower if the weather continues to be sunny, shaking constantly while enabling an air outlet to be aligned with the flowers and fruitsof the strawberries, blowing the aging pedals to the ground, leaving no residue of the aging petals on the fruit; D, clearing the fruit and the leave infected with the grey mould at regular intervalsin the blossom stage, putting in a plastic bag; and E, enabling inflorescences of the strawberry to blossom in batches within the same production period, and finishing harvesting from the full-bloom period of the second batch of flowers to the following year. The incidence rate of the grey mould of the strawberry fruit is obviously reduced, the amount of the chemical pesticide applied is effectively reduced, and the quality of the strawberry fruit is guaranteed.

Description

technical field [0001] The invention relates to the technical field of strawberry disease prevention and control, and more specifically relates to an environment-friendly method for preventing and treating gray mold of strawberry fruit. Background technique [0002] Strawberry is a perennial evergreen herb of the Rosaceae (Rosaceae) genus Fragaria, and is an important economic crop widely cultivated in the world. In recent years, my country's strawberry planting area and output have continued to increase. In 2012, my country's strawberry planting area reached 100,500 hectares, with a total output of 2.761 million tons, ranking first in the world in both planting area and output. Botrytis cinerea is one of the most devastating plant diseases in the world, and it is also an important disease in the strawberry production period in my country. Because the warm and humid environmental conditions during the strawberry growth period are very conducive to the occurrence of Botrytis...
