Problems solved by technology

[0005] At present, the use of azadirachtin as a pesticide is mainly through surface spraying and root irrigation. The surface spraying method will accelerate the degradation of active ingredients due to factors such as high temperature and ultraviolet rays, which will affect the expected effect of the pesticide; Absorption and osmosis reduce the efficiency of plant uptake of pesticides

Embodiment 1

[0025] Example 1: Take 5 grams of the azadirachtin mother drug containing 39.13% azadirachtin by weight, pre-dissolve it with 10 ml of 95% ethanol, and mix the azadirachtin mother drug with ethanol with a buffer solution of pH 5 After the solution is diluted to 150 ml, inject the medicine according to the dosage of 0.5mL / cm, 0.7mL / cm, and 0.9mL / cm (diameter at breast height). The injection site is 30cm from the ground, and the injection depth reaches the xylem. One plant is One repetition, a total of three repetitions and a clear water control.

Abstract

The present invention discloses a truck injection agent with nimbin, which consists of nimbin, latent solvent, osmotic agent, mixing agent and diluent, at the same time, the invention discloses the application of the truck injection agent with nimbin in the truck injection field, namely that the truck injection agent is injected into the truck directly. The injecting part is positioned on the truck with more than 10 cm from the ground, and the injecting depth reaches the xylem. By the method of direct injection, the medicine enters directly into the plant tissue, which reduces the influence of environmental factor to the nimbin, ensures a good suction rate of the plant to the nimbin and reduces correspondingly the relative usage of the nimbin, moreover, the nimbin after entering the plant tissue is able to be conducted primely so as to have longer lasting performance, thus protecting the target plant in a better manner.

Description

Technical field [0001] The invention relates to a dry injection agent containing azadirachtin and the application of azadirachtin in fruit trees, gardens and forestry by using a dry injection method to prevent and control diseases and insect pests. It belongs to the field of pesticides. Background technique [0002] Azadirachtin is a high-efficiency, low-toxicity, low-residue, environmentally friendly natural pesticide extracted from plants in the Meliaceae family, such as Azadirachtin indica, which is safe and non-toxic to humans and animals, and has no environmental pollution. It is currently one of the most respected biological pesticides. 1. It can be widely used to prevent and control agricultural pests, mites, nematodes and other pests. Its mode of action is mainly antifeeding / repellent effect, reproduction inhibition effect, oviposition repellent effect, insect growth regulation effect, etc. It has the advantages of not being prone to drug resistance, not harming natural e...
