Problems solved by technology

However, due to the lack of ideal dry-on formulations, it is difficult to apply in actual production
At present, the dry-applied agents used in production, such as Bordeaux pulp, methylthionaphthine acetic acid, etc., all have the disadvantages of being not resistant to rain erosion and having a short duration of effect
Applying the agent on the branches before winter or during the dormant period of the tree body in March, the effect of the agent is difficult to maintain until the critical period of pest infestation from June to August, and the control effect of the applied agent cannot be exerted

Embodiment 1

[0045] Example 1 The effect of different coated dry substrates on the release and digestion of bactericidal and insecticidal active ingredients

[0046] 1. Experimental materials: In this example, Liang Zhuang and talc were used as control substrates to test the release of four kinds of latex paint coating dry substrates (see Table 1) on 6 kinds of bactericidal active ingredients and insecticidal active ingredients (see Table 2) And degradation rate.

[0047] 2. Experimental method: 6 kinds of coated dry substrates were set up in the experiment. Use different coated dry substrates, each with a mass of 500ml (the talcum powder can be made into a paste with water before use), according to the dosage given in Table 2, add 6 different fungicides and killers to each substrate. One of the ingredients in the insect agent is fully stirred and mixed evenly to prepare different coating dry formulations.

[0048] Pour each dry-coated preparation into three stainless steel trays, spread them i...

Embodiment 2

[0061] Example 2 Effect of coated dry substrate on the antibacterial effect of bactericidal active ingredients

[0062] 1. Test materials: This example tests the effect of four dry coated substrates on the antibacterial effects of two bactericidal active ingredients. The four substrates are Nippon New Shili Yaguang interior wall latex paint, China Resources Jingwei Jiayi white environmentally friendly interior wall latex paint, Sankeshu Zhenshili interior wall latex paint and Dulux 1000 professional leisurely home interior wall white latex Lacquer (see Table 1). The two effective bactericidal ingredients are 50% carbendazim wettable powder and 25% pyraclostrobin EC. The manufacturer and dosage are shown in Table 2.

[0063] 2. Test method: 4 kinds of substrates and 2 kinds of fungicides are mixed to make 8 kinds of dry-coated preparations, with 2 kinds of fungicide aqueous solutions as the control, there are 10 combinations in all tests, and each combination is set with 2 petri di...

Embodiment 3

[0069] Example 3 Four kinds of dry coated substrates adhesion and rain erosion resistance

[0070] 1. Test material: Bordeaux pulp (copper sulfate: quicklime: 1% soy milk = 1:3:15) was used in this example. figure 1 .F) and pretty pile( figure 1 .G) As a control substrate, the adhesion and rain resistance of four dry-coated substrates were tested. The four substrates are three trees Zhenshili interior wall latex paint ( figure 1 .A), Nippon New Shishili Yaguang interior wall latex paint ( figure 1 .B), China Resources Jingwei Jiayi White White Environmental Protection Interior Wall Latex Paint ( figure 1 .C), Dulux 1000 professional leisurely home interior wall white latex paint ( figure 1 .D) (see Table 1).

[0071] 2. Test method: In late March, the four kinds of dry substrates, Bordeaux grout, and stubs were directly coated on the tempered glass plate with a brush. The coating area of ​​each substrate was 30cm*20cm. Stand the glass plate on the side of the wall, the angle betwee...

Abstract

The invention discloses a trunk coating preparation for preventing and treating fruit tree seedling-borne diseases and insect pests, a preparation method and application of the trunk coating preparation. The trunk coating preparation comprises a trunk coating matrix, a bactericidal active component and an insecticidal active component, wherein the trunk coating matrix is a white interior wall water-based coating material for buildings, the bactericidal active component is one of a benzimidazole bactericide compound, a methoxy acrylate bactericide compound and a triazole bactericide compound, and the insecticidal active component is one of neonicotinoid, organophosphorus, pyrethroid and tetronic acid insecticide compounds. According to the invention, the trunk coating preparation can be used for directly coating or spraying branches and trunks after fruit tree seedlings come out of a nursery or before planting, can form a white physical protective film layer containing bactericidal andinsecticidal active ingredients on branches and trunks, can effectively remove various diseases and pests on the latent zone of the fruit tree nursery stock and protect newly planted nursery stock from being damaged by the diseases and pests in the rejuvenation period and the young tree growth period, provides a set of new medicament and new treatment technology for fruit tree nursery stock pre-planting treatment, and can effectively improve the prevention and control level of fruit tree nursery stock branch diseases and pests.

Description

Technical field [0001] The invention relates to the field of agricultural sterilization and insecticides, in particular to a dry coating preparation for preventing and controlling diseases and insect pests transmitted by fruit tree seedlings, and a preparation method and application thereof. Background technique [0002] Seedling-borne diseases and insect pests refer to the diseases and insect pests that can be transmitted with fruit tree seedlings. The common ones include ring disease, rot disease, anthracnose, gum disease, cotton aphid, scale shells, branched beetles, wood sac moth, chitin, etc. . The pathogens and pests of seedling-borne diseases and insect pests mainly lurking on the fruit branches and overwintering, and can spread to new orchards with the spread of seedlings. Once the seedling-borne diseases and insect pests enter the new orchard with the seedlings, they are often difficult to eradicate, causing great harm to fruit production. For example, apple seedlings ...
