Embodiment 1

[0030] A biological control method for botrytis cinerea. Firstly, the blue fruit grinding liquid of snakeberry with a mass fraction of 0.4-0.6% is prepared, placed in a plastic bucket, and sealed and stored in a cool place; The ground and vines of the grape orchard are sprayed with the liquid snake berry blue fruit at least once; secondly, during the flowering period of the grapes, the grape vines are sprayed with the blue snake berry fruit liquid at least once; then, in the young fruit stage of the grapes, the grape The tree is sprayed at least once with the grinding liquid of the green fruit of the snake berry; finally, in the ripening period of the grapes, the grinding liquid of the blue fruit of the snake berry is sprayed at least once to effectively prevent and control botrytis cinerea.

Embodiment 2

[0032] Inhibition experiment of the grinding liquid of snake berry stem, leaf, green fruit and red fruit on the conidia of Botrytis cinerea.

[0033] 1. Experimental materials:

[0034] (1) Snakeberry stem grinding liquid with a mass fraction of 0.5%;

[0035] (2) Snakeberry leaf grinding liquid with a mass fraction of 0.5%;

[0036] (3) Grinding liquid of snakeberry green fruit with a mass fraction of 0.5%;

[0037] (4) Red snakeberry fruit grinding liquid with a mass fraction of 0.5%;

[0038] 2. Experimental method: Pour the experimental materials (1)-(4) into PDA medium with a diameter of 75mm, spread evenly with a triangular glass rod, and then use a hole punch with a diameter of 12mm to prepare activated ash Botrytis bacterium cake, inoculate the mycelium face down in the center of the PDA medium coated with experimental materials (1)-(4) on the surface, the relative humidity of the PDA medium is controlled at 92-97%, pH=3-5, and Placed in a constant temperature incu...

Embodiment 3

[0046] 1. Experimental time: 2013;

[0047] 2. Experimental location: a vineyard in Hefei City, Anhui Province;

[0048] 3. Experimental method:

[0049] Divide a piece of vineyard into five parts in turn, each part is three rows;

[0050] The first part does not do any treatment in the early stage; after a large number of grapes get sick, in order to reduce economic losses, the green fruit grinding liquid of snakeberry with a mass fraction of 0.5% is used for treatment;

[0051] Second part adopts the method described in embodiment 1 to process, and adopting massfraction is 0.4% snake berry cyan fruit grinding liquid, all sprays once in each period;

[0052] The third part adopts the method described in embodiment 1 to process, adopting massfraction to be 0.5% snake berry cyan fruit grinding liquid, all spraying once in each period;

[0053] The fourth part adopts the method described in embodiment 1 to process, adopting massfraction to be 0.6% snake berry cyan fruit grind...

Abstract

The invention discloses a biological prevention and control method for grape gray mold. 0.4-0.6% of Indian strawberry cyan fruit grinded liquid, by mass, is prepared, placed in a plastic bucket and then stored in a shade place in a sealed mode for standby utilization; firstly, from February to March in the Gregorian calendar, the Indian strawberry cyan fruit grinded liquid is sprayed at least one time on the ground in a grape orchard and grape vines; secondly, at the flowering phase of grapes, the Indian strawberry cyan fruit grinded liquid is sprayed at least one time on the grape vines; then, at the young fruit phase of the grapes, the Indian strawberry cyan fruit grinded liquid is sprayed at least one time on the grape vines; finally, at the mature phase of the grapes, the Indian strawberry cyan fruit grinded liquid is sprayed at least one time on the grape vines, so that the grape gray mold is prevented and controlled. The biological prevention and control method not only can achieve the purpose of disease prevention and control, but also can prolong the guarantee period of the grapes, and is more natural, environmentally friendly and lower in cost; in addition, Indian strawberries can prevent flies and insects from biting the grapes, so that the sanitation condition of the grapes is greatly improved.

Description

technical field [0001] The invention relates to the field of plant protection, in particular to a biological control method for botrytis cinerea. Background technique [0002] Botrytis cinerea: Commonly known as "rotten spike", also known as grape gray rot, the pathogen is Botrytis cinerea. Botrytis cinerea is a relatively serious disease in the world at present, and it causes the most serious loss among all storage diseases. [0003] Symptoms of damage: Inflorescences and young fruits are susceptible to disease. First, light brown, water-soaked lesions appear on the pedicel, small fruit stem or cob, and then the lesions turn brown and soft rot. When the air is humid, rats can appear on the lesions. Gray mold, that is, the conidiophores and conidia of pathogenic bacteria. When the air is dry, the susceptible inflorescences and young fruits will gradually lose water and shrink, and then dry up and fall off, resulting in a large number of flower and fruit drop. In severe cas...
