Embodiment 1
[0017] 1. Grind dried saponins 5%, scutellaria baicalensis 10%, banlangen 20%, licorice 10%, bamboo rutabaga 10%, pass through a 40-mesh sieve, and soak in solution for 24 hours separately or in combination;
[0018] 2. Separately or mixed extraction under reflux conditions, extraction temperature 80°C, extraction time 3h, extraction 2 times, the two extracts were combined, the extracts were concentrated and dissolved to 1 / 3 of the crude drug weight, and set aside;
[0019] 3. In the reaction kettle, add 15% of the stabilizer and 5% of the penetrating agent according to 25% of scallion, and mix thoroughly at 50°C to obtain a fungicide.

Abstract
The invention discloses a traditional Chinese medicine composition for preventing and controlling crop pest and preparation method of the traditional Chinese medicine composition, relates to an agricultural medicament for preventing and controlling crop pest, and belongs to the field of novel pesticides. The traditional Chinese medicine composition is characterized by comprising the following raw materials by weight percent: 5-10% of Chinese honeylocust fruit, 5-10% of radix scutellariae, 15-20% of radix isatidis, 5-10% of liquorice, 5-10% of caulis bambusae in taeniam, 25-35% of longstamen onion bulb, 15-20% of stabilizer, and 5-10% of penetrating agent; the above raw materials are decocted for 40min. The traditional Chinese medicine composition has the beneficial effects that effective ingredients of the traditional Chinese medicine preparation can directly achieve disease tissue of the tree body to kill the germ cells through reasonable ratio; not only can the germs be completely killed, but also the bark and the tree body cannot be injured; the field dosage is greatly reduced, the environment pollution and pesticide residue are effectively reduced, and the production cost and the use cost are lowered; the action mechanisms of the effective ingredients in the sterilizing composition are different from each other so that the disease resistance is overcome and the production of the disease drug resistance is delayed.
Description
technical field [0001] The invention relates to an agricultural medicament for preventing and controlling crop diseases and insect pests, and belongs to the field of novel pesticides, in particular to a traditional Chinese medicine composition for preventing and controlling crop diseases and insect pests and a preparation method thereof. Background technique [0002] The application of chemically synthesized pesticides has the characteristics of good control effect and fast action, and is currently one of the important means of pest control. However, a large number of long-term and irrational use of chemically synthesized pesticides, especially the application of highly toxic and high-residue pesticides, has resulted in excessive pesticide residues, polluted the environment and agricultural products, and endangered the health of humans and animals; pests and diseases have developed resistance to pesticides, reduced control effects and even killed Serious natural enemies will...
