Problems solved by technology

[0004] Among the above three methods, agricultural control is an auxiliary method, and its main purpose is to isolate the transmission route of pathogenic bacteria. Chemical control is mainly for active control when the disease occurs. Biological control is an emerging control method, so chemical control is still the main method used, but Extensive use of chemicals will cause drug residues in the crops, and the effect is not very good

preparation example Construction

[0031] The preparation method comprises the following steps:

[0032] ⑴Collect the cattail grass hay harvested after the frost, and then cut it into 15-30 cm sections;

[0033] ⑵Add the cut hay to 10 times the weight of water for decoction, and continue to decoct on low heat for 20 minutes after boiling;

[0034] ⑶ Leave it to cool naturally, filter out the residue, and add potassium sorbate with a liquid weight of 0.3‰ to make an extract.

[0035] 2. Use the fresh grass of cattail grass as raw material

[0036] The preparation method comprises the following steps:

[0037] ⑴Chop the fresh cattail grass harvested from July to August;

[0038] ⑵Add the chopped fresh grass to the equipment to squeeze the juice;

[0039] (3) Filter the solid-liquid mixture to remove the residue, and add potassium sorbate with a liquid weight of 0.3‰ to make an extract.

Embodiment 1

[0041] Select 30 mu of strawberry land and divide it into two groups of 10 mu each, of which 10 mu is named A, the other 10 mu is named B, and the other 10 mu is named C. The composition and pH of the soil of A, B and C The same, the temperature, humidity, wind, and light of the area are the same, the water source is the same, and the fields are cleaned in the same way.

[0042] The same strawberry variety was planted in A, B and C, and the plant density and management method were the same.

[0043] A uses the medicament of the present invention, B uses traditional chemical medicament, and C does not use any medicament.

[0044] In A: take the fresh grass of cattail grass as raw material, and use it according to the following method:

[0045] (1) The extract is mixed with water at a weight ratio of 10:1 to prepare a spray;

[0046] ⑵In sunny days, after three o'clock in the afternoon, use an electrostatic sprayer to spray the whole plant, and the dosage is 50 kg per mu;

[...

Embodiment 2

[0053] Select a 30-acre greenhouse for planting tomatoes and divide it into two groups, each group is 10 acres, of which 10 acres are named A, the other 10 acres are named B, and the other 10 acres are named C. The composition and pH of the soil of A, B and C The same, the temperature, humidity, wind, and light of the area are the same, the water source is the same, and the greenhouses are cleaned in the same way.

[0054] In A, the cure rate is 100%, and gray mold has been completely prevented and treated within 2 years.

[0055] In B, the cure rate is about 93%, and the recurrence rate is relatively high.

[0056] In C, the yield was reduced in a large area, and some fields had no yield.

Abstract

The invention relates to a crop gray mold prevention and treatment agent, which takes an extract of a leaf of cattail as a raw material. The extract comprises a preservative. According to the agent, the leaf of the cattail is taken as the raw material; the extract can be obtained by decocting or juicing, then is sprayed onto crops after diluted with water, and can exert a prevention function when the crops are not attacked, and exert a good treatment function when the crops are attacked; a cure rate reaches 100% according to a field test; the agent not only can prevent and treat gray mold, but also has an obvious preventive effect on other fungus diseases; and in addition, the leaf of the cattail is a wild vegetable, and can be eaten, so that the problem of pesticide residue cannot occur in actual use.

Description

technical field [0001] The invention belongs to Technical Field of Crop Botrytis Control , especially a crop botrytis control agent and a preparation method thereof. Background technique [0002] Botrytis cinerea is a common and difficult to control fungal disease of crops in open fields and protected areas. It is a low-temperature and high-humidity disease and is mainly caused by Botrytis cinerea. It is a high-incidence period, which can damage flowers, fruits, leaves, stems, etc. When green fruits are infected, the remaining stigmas or petals are mostly infected first, and then expand to the fruit, resulting in off-white skin with a thick gray mold layer; when the leaves are infected, they start from the tip of the leaf and expand inward along the veins. When the disease occurs, if the control is not timely, it will cause a large area of ​​crops to be infected, resulting in a reduction in production, and eventually cause serious economic losses to the growers. [0003] ...
