Embodiment 1

[0073] A control method for grape root-knot nematode, comprising the following steps:

[0074] 1) Ecological governance:

[0075] ①Apply Deflavin microbial fertilizer;

[0076] ② Apply Woyiduo microbial fertilizer;

[0077] 2) Agricultural control:

[0078] ① Use resistant varieties or rootstocks;

[0079] ②Previous crops avoid good hosts of nematodes such as tomatoes, grapes, and deciduous fruit trees;

[0080] 3) Quarantine:

[0081] Strict quarantine, do not introduce seedlings from diseased areas, if necessary, strictly disinfect and soak in hot water at 50°C for 10 minutes;

[0082] 4) Physical control:

[0083] Do a good job in rural sanitation, pull out seriously diseased plants, remove diseased plant residues, pick out insect-bearing roots, and destroy them in a centralized manner;

[0084] 5) Biological control:

[0085] ① Intercropping non-host plants such as pyrethrum and hemp in the vineyard can block the spread of pathogens and effectively reduce diseases;...

Abstract

The invention relates to a preventing and treating method for a grape root-knot nematode disease. The method includes the steps that 1, ecological treatment is performed, wherein Difulai microorganism fertilizer is applied, and HYT microorganism fertilizer is applied; 2, agricultural prevention and treatment are performed; 3, in quarantine inspection, quarantine inspection is performed strictly, seedlings are not introduced from the diseased region to be planted, and if it is necessary to introduce the seedlings from the diseased region to be planted, the seedlings should be strictly sterilized and soaked in hot water of 50 DEG C for 10 minutes; 4, physical prevention and treatment are performed; 5, biological control is performed; 6, chemical prevention and treatment are performed, wherein 1500-2000 g of 10% fosthiazate granules per mu are applied in holes in transplanting or mixed with fine soil to be applied in furrows after planting. In this way, the grape root-knot nematode disease can be effectively prevented, meanwhile, agricultural prevention and treatment, physical prevention and treatment and other measures are taken to perform comprehensive prevention and treatment to lower the average incidence of the grape root-knot nematode disease, the yield is increased, the grape grade is remarkably increased, and good economic benefits are achieved.

Description

technical field [0001] The invention relates to a method for preventing and treating grape root-knot nematode disease, belonging to the technical field of plant protection. Background technique [0002] Grape root-knot nematode disease seldom kills the plants, usually the plants go from exuberance to decline, and are prone to adversity reactions. Due to the damage of root-knot nematodes in new or newly planted vineyards, the young plants cannot grow. Although some grow barely, they cannot fully grow up and fail to reach the shelf surface, resulting in inability to be trimmed and pruned. [0003] Harm symptoms: [0004] (1) Roots: After root-knot nematodes damage grape plants, they cause absorption roots and secondary roots to expand and form root knots. A single nematode can cause very small nodules, and an infestation by multiple nematodes can cause larger knots. Severe infestation can cause all absorbing roots to die, cause poor root growth, stunted growth, short latera...
