Problems solved by technology

[0012] However, the workload of agricultural protection methods is large, which puts a lot of pressure on laborers; the use of pesticide protection will not only affect the growth of potatoes, but also the residual pesticides in potatoes will endanger people's health and pollute the environment

Embodiment 1

[0021] A kind of biological control method of potato late blight, first prepare the ginger flower fruit grinding solution with a mass fraction of 3% to 5%, put it in a plastic bucket, and keep it sealed in a cool place; first, in the Gregorian calendar from March to April, the potato The ground and potato plants of the garden are sprayed with ginger flower fruit grinding liquid at least once; then, during the germination stage of potatoes, the potato plants are sprayed with ginger flower fruit grinding liquid at least once; finally, in the potato seedling stage, potato plants are sprayed with Potato late blight can be effectively prevented and controlled by at least one ginger flower fruit grinding solution.

Embodiment 2

[0023] Inhibition experiment of ginger flower stem, leaf and fruit grinding liquid on conidia of Phytophthora infestans flagellin subphylum.

[0024] 1. Experimental materials:

[0025] (1) ginger flower stem grinding liquid with a mass fraction of 4%;

[0026] (2) Ginger flower leaf grinding liquid with a mass fraction of 4%;

[0027] (3) Ginger flower fruit grinding liquid with a mass fraction of 4%;

[0028] 2. Experimental method: Pour the experimental materials (1)-(3) into PDA medium with a diameter of 75 mm, spread evenly with a triangular glass rod, and then use a hole punch with a diameter of 12 mm to prepare the activated PDA medium. Phytophthora flagellin subphylum fungus cake, mycelium face down inoculated in the center of the PDA medium coated with experimental materials (1)-(3), the relative humidity of the PDA medium is controlled at 95-97%, And placed in a constant temperature incubator at 22°C for 10 hours in the dark.

[0029] 3. Experimental results:

Embodiment 3

[0032] 1. Experimental time: 2014;

[0033] 2. Experimental location: a potato garden in Anhui Province;

[0034] 3. Experimental method:

[0035] Divide a potato garden into five equal parts;

[0036] The first part does not do any treatment in the early stage; after a large number of potatoes get sick, in order to reduce economic losses, the ginger flower fruit grinding liquid with a mass fraction of 4% is used for treatment;

[0037] Second part adopts the method described in embodiment 1 to process, and adopting massfraction is 3% Ginger Flower fruit grinding liquid, all sprays once in each period;

[0038] The third part adopts the method described in embodiment 1 to process, adopting massfraction to be 4% ginger flower fruit grinding liquid, all spraying once in each period;

[0039] The fourth part adopts the method described in embodiment 1 to process, adopting massfraction to be 5% ginger flower fruit grinding liquid, all spraying once in each period;

Abstract

The invention provides a biological prevention and treatment method for the late-blight disease of potato. The biological prevention and treatment method comprises the following steps: preparing hedychium coronarium fruit grinding fluid with a mass fraction of 3% to 5%, then carrying out placing in a shade place, and carrying out sealed preservation for standby application; in March to April of the solar calendar, spraying the hedychium coronarium fruit grinding fluid on the potato orchard ground and potato plants for at least one time; in the germination stage of the potato, spraying the hedychium coronarium fruit grinding fluid on the potato plants for at least one time; and finally, in the seedling stage of the potato, spraying the hedychium coronarium fruit grinding fluid on the potato plants for at least one time. Field test results show that the biological prevention and treatment method provided by the invention has good prevention and treatment effects on the late-blight disease of the potato, has simple manufacturing method and low cost, is free of pesticide residue in plants, and is more natural and environmentally friendly; in addition, hedychium coronarium also has functions of warming the middle for invigorating the stomach, relieving exterior syndromes, inducing perspiration, warming the middle for dispersing cold, relieving pains, etc., so added values of the potato are increased.

Description

technical field [0001] The invention relates to the field of plant protection, in particular to a biological control method for potato late blight. Background technique [0002] Potato late blight is caused by the infection of Phytophthora infestans (Mont.) de Bary. Late blight is one of the most important fungal diseases in the main potato producing areas, and its initial source of spread is adjacent potato fields or tomatoes, weeds and organic compost. [0003] Symptoms of harm: When the leaves are infected, water-soaked green-brown spots will appear on the tip or edge of the leaves, with a light green halo around the spots. When the humidity is high, the spots will expand rapidly and turn brown, and produce a circle of white mold, that is, cysts Stems and sporangia, especially on the back of leaves are the most obvious; when dry, the lesions turn brown and dry, brittle and easy to crack, no white mold, and the expansion speed slows down. Brown streaks appear on stems or...
