AI Technical Summary

Problems solved by technology

In addition, problems such as drug resistance and microbial degradation caused by the long-term frequent use of a single type of nematicide have weakened the effect of these nematicides
Driven by interests, farmers often choose to increase the use of pesticides, which results in increased production costs and substandard pesticide residues
At present, the auxiliary biological agents on the market are mostly through fungal predation and root probiotics, and their control effect is very dependent on their colonization ability, so the control effect is very unstable in different habitats.
At the same time, the use of common root-knot nematode disease control drugs itself often causes phytotoxicity of crops, reducing crop biomass and yield.

Embodiment 1

[0061]Example 1: Prevention and treatment of wettable powder on the roots of tomatoes

[0062]Formulation: 20% Composition (0.65% HP, 13.0% SP, 6.35% IM), 2.5% phenol polyoxyethylene (wetting agent), 2.5% lignozoate (dispersant), 0.5% ring Oxygen soybean oil (suspending agent and stabilizer), the margin is a talc powder (filler). The above raw materials is prepared by mixing, ultra-micro gas flow, and prepared by mixing process steps. In addition, 19.35% (13.0% SP, 6.35% IM) wettable powder formula differed in that no HP was not added, and the rest were the same. The active ingredient in the 5% HP wettable powder contains only 5% HP, and the active ingredient in 19.2% IM wettable powder contains only 19.2% IM, and the remaining excipients and aids are the same. 70.1% of the SP wettable powder contains only 70.1% of the fig-proposed polymerfum fermentation, and the remaining excipients and aids are the same.

[0063]This example is applied to the prevention and treatment of tomato roots. I...

Embodiment 2

[0067]Example 2 20% wettable powder on the control of cucumber roots

[0068]The formulation is the same, which is applied to the control of the root of cucumber. In January 2018, in Shouguang City, Shandong Province, Shouguang City was used in a greenhouse greenhouse, which was severely infected with root-knotted nematode disease. The roots in the greenhouse were mainly rooted in the southern roots, including a small amount of peanuts. The test method and design are the same, the test object used is cucumber seedlings, and the variety is "Winter Wei". After 30 days, the control effect was detected, and the test items included the roots, cucumber pairs of diced blade (leaf area = leaf length × leaf width × 0.743), high strain, cucumber production. The specific results are shown in Table 4.

[0069]Table 4

[0070]

[0071]The results showed that HP treatment in a single-agent treatment was lowered to be 28.85%, 19.2% IM wettable powder was higher, 82.35%. 20% of the wettable powder containing s...

Abstract

The invention belongs to the field of agricultural plant protection, in particular to a signal protein-containing composition for controlling root-knot nematodes, a preparation method and application thereof. The composition comprises active component A signal protein, active component B biocontrol fungus spore powder, active component C non-fumigation nematocide; The nematode control method achieves the purpose of preventing and controlling root-knot nematode through joint action by improving the stress resistance ability of crops, increasing the growth vitality of crops, weakening the ability of root-knot nematode infection and the ability to generate fixed feeding sites after infection. ; The components of the composition show obvious synergistic effect within a certain proportion range, significantly improve the control effect compared with the single use of the components, reduce the dosage, and reduce the possible impact of a small amount of synthetic chemicals on the ecological environment. residual.

Description

Technical field[0001]The present invention belongs to the field of agricultural plant protection, and more particularly to a signaling protein composition for preventing root knot and its preparation method and application thereof.Background technique[0002]Root knot wormMeloidogyne SPP.) is a native disease, and its host is very extensive, and almost all of the vascular bundles can be infected, so most vegetable crops are its good host. In the root nest, in addition to the second-age larvae of the intrusion, other periods are in the roots or ovars. A year of age larvae formed in the ovar shell and formed a second-age larvae with a needle, and the second-age larvae was pierced into the soil. The second-age larvae infected is in the water of the soil gap, finds the right host and infects the root of the root of the root, stop the cell interval near the root in the root. Here, the second-age larvae secretes special substances stimulates surrounding plant cells to form huge cells in nor...
