Embodiment Construction

[0012] The invention relates to a method for preventing and controlling vegetable root-knot nematode disease by using aluminum phosphide to fumigate the soil: use 22.5-75 kg of 56% aluminum phosphide tablet pesticide composition per hectare, and ditches or holes the soil about 30 centimeters deep , manually sprinkle the agent in the above-mentioned ditches or holes, and then cover with soil; or use machinery to directly apply it to the soil at a depth of about 30 cm, and then cover it with a plastic film, fumigate the soil for 5 to 7 days, and then sow. and transplanting crops or vegetables. According to the above method of use, the greenhouse vegetables suitable for planting in the soil fumigated with 56% aluminum phosphide tablet can be various vegetables such as tomato, cucumber, zucchini, eggplant, pepper, kidney bean, and cowpea. It is also suitable for treating soil in the open field and preventing and controlling root-knot nematode diseases of economic crops such as gin...

Abstract

The invention relates to a method for preventing and controlling a vegetable root knot nematode disease by fumigating soil with aluminium phosphide. In the method, 56 percent of aluminium phosphide tablets are fertilized into soil with the depth about 30 centimeters, a soil surface is covered by a plastic film, nematodes can be fast killed by a phosphine (PH3) gas released by the aluminium phosphide, and fumigating processing is carried out for 5-7 days so as to efficiently prevent and control the root knot nematode disease of a plant. The invention is not only used for protected-land vegetables but also widely used for preventing and controlling the nematodes on peanuts, vegetables, tobacco and multiple crops which are grown on openground and has high application value and very obvious economic and social benefits.

Description

(1) Field of invention: [0001] The invention relates to a method for using 56% aluminum phosphide (aluminum phosphide) tablet composition and applying the aluminum phosphide tablet composition to fumigate soil to control vegetables and other crop root-knot nematodes. (2) Technical background: [0002] Aluminum phosphide is mainly used at home and abroad as a fumigation insecticide for grain, Chinese medicinal materials and other stored products. Aluminum phosphide can absorb water vapor from the air and gradually decompose to produce phosphine (PH 3 )gas. Phosphine is a colorless, highly toxic gas with an acetylene odor. The specific gravity of the gas is 1.183, slightly heavier than air, but lighter than other fumigant gases. It has relatively strong permeability and diffusibility, and is more convenient to use. Through the respiratory system of the pest or through the membrane of the body wall, it penetrates into the insect body, causing the pest to be poisoned and kil...
