Embodiment 1

[0014] Embodiment 1 preparation active ingredient content is the water dispersible granule of 5.5%

[0015] The specific ratio is:

[0016] Raw material dosage (parts by weight)

[0017] Trichoderma harzianum spore powder 0.5

[0018] Chrysanthemum root powder 2.5

[0019] 6% oligosaccharide·catenin 2.5

[0020] Sodium lignosulfonate 7

[0021] Clay and plaster top up to 100

[0022] The preparation method comprises: weighing Trichoderma harzianum spore powder, chrysanthemum chrysanthemum root powder, 6% oligosaccharide-catenin, sodium lignosulfonate, clay and gypsum, mixing them uniformly, and preparing the active ingredient content of 5.5% by jet milling. Wettable powder; after granulation, it can be made into 5.5% water-dispersible granules.

Embodiment 2

[0023] Example 2 Preparation of water-dispersible granules with an active ingredient content of 8%

[0024] The specific ratio is:

[0025] Raw material dosage (parts by weight)

[0026] Trichoderma harzianum spore powder 0.5

[0027] Chrysanthemum root powder 2.5

[0028] 6% oligosaccharide·catenin 5

[0029] Sodium lignosulfonate 7

[0030] Clay and plaster top up to 100

[0031] The preparation method comprises: weighing Trichoderma harzianum spore powder, chrysanthemum chrysanthemum root powder, 6% oligosaccharide-catenin, sodium lignosulfonate, clay and gypsum, mixing them evenly, and preparing the active ingredient content of 8% by jet milling. Wettable powder; after granulation, it can be made into 8% water-dispersible granules.

Embodiment 3

[0032] Example 3 Preparation of granules with an active ingredient content of 13% (disintegration)

[0033] The specific ratio is:

[0034] Raw material dosage (parts by weight)

[0035] Trichoderma harzianum spore powder 0.5

[0036] Chrysanthemum root powder 2.5

[0037] 6% oligosaccharides·catenin 10

[0038] sodium bicarbonate 1

[0039] Clay and plaster top up to 100

[0040] The preparation method comprises: weighing Trichoderma harzianum spore powder, chrysanthemum chrysanthemum root powder, 6% oligosaccharide chain protein, sodium bicarbonate, clay and gypsum, mixing uniformly, adding binder water to the mixture, mixing, granulating and Drying is prepared into granules with an active ingredient content of 13%. Wherein, the added amount of the water is 7% of the total weight of the mixture, and the water is removed after drying, so the weight of the water is not included in the weight of the granules.

Abstract

The invention provides a preparation for inhibiting plant nematode disease. The preparation is composed of effective components, auxiliaries and fillers, wherein the effective components comprise 0.2-4wt% of trichoderma harzianum spore powder, 2%-20wt% of crowndaisy chrysanthemum root powder and 2%-10wt% of 6% oligosaccharide-chain protein. The pesticide composition is prepared from the trichoderma harzianum spore powder, the crowndaisy chrysanthemum root powder and the 6% oligosaccharide-chain protein by mixing, and the content of plant nematodes is rapidly killed from the source, so that theproduct safety quality is improved.

Description

technical field [0001] The invention belongs to the field of pesticides, in particular to a preparation for inhibiting plant nematode diseases. Background technique [0002] Among the four major pathogens that cause plant infectious diseases, plant parasitic nematodes are more harmful than bacteria and viruses, and are second only to fungal diseases. Plant parasitic nematodes cause about 100 billion US dollars of losses in world agricultural production every year, and root-knot nematodes (Meloidogyne spp.) are the most harmful type of plant parasitic nematodes. More than 1000 eggs. Root-knot nematode usually has no obvious host specialization, and can infect more than 3000 species of plants, belonging to 114 families, including monocotyledonous plants, dicotyledonous plants, herbaceous plants and woody plants. Crops, fiber crops, tobacco, tea, fruit trees, vegetables, medicinal herbs and flowers can cause severe losses. After being harmed by it, the quality of crops will ...
