Problems solved by technology

Since the main drugs used to prevent and treat the disease for many years are carbendazim, saccharin, triadimefon, etc., drug resistance has appeared in production; Shigao, polyoxin, Fuxing, and A Misida and other pesticides are mostly imported from abroad, and the price is high, which is difficult for farmers to accept in large-scale production
Moreover, chemical pesticides have problems such as relatively high toxicity and heavy pollution, which are not good for people's health. In the production of green food, it is necessary to develop high-efficiency and low-toxic botanical pesticides

Embodiment 1 Embodiment 5

[0008] Use a small amount of acetone to dissolve the original drug of dark russin and the original drug of acetoallin, and mix them according to different proportions to make 5 mixed mother solutions. 3:1 and 5:1, these five mixed solutions are respectively referred to as Embodiment 1 to Embodiment 5.

[0009] Embodiment 1~Example 5 and dark russin, ethyl allicin are each prepared with sterile water 100ml, the concentration is the liquid medicine of 2000 μ g / ml, and its inhibitory action to strawberry powdery mildew is carried out indoor measurement, and measurement process is as follows:

[0010] 1. Preparation of powdery mildew conidia suspension

[0011] Fresh conidia on leaves of strawberry plants were collected, rinsed with sterile water, and made into conidia suspension (8-10×10 / mL). From the preparation of the conidia suspension to the completion of the inoculation should be limited within 2h.

[0012] 2. Preparation of nutrient solution

[0013] It adopts the genera...

Embodiment 6

[0024] Compound dark russin: acetoallin at a weight ratio of 1:1, and then prepare it with grass vinegar, auxiliary agents and fillers to make a fungicide preparation, wherein dark russin and acetoallicin account for 30% of the total weight of the preparation , grass vinegar accounts for 10% of the total weight of the preparation, auxiliary agents account for 6% of the total weight of the preparation (wherein the surfactant sodium dodecylbenzene sulfonate is 3%, the wetting agent sodium lignosulfonate is 3%), and the rest are fillers.

[0025] Use the preparation of embodiment six to prevent and control the crops represented by strawberry and grape in fruit trees respectively, and compare and test the control effect of powdery mildew, the method is as follows:

[0026] Set preparation 60 grams, 80 grams, 100 grams per mu, 80% ethyl allicin EC 40 grams per mu, 30% dark Russell WP 100 grams per mu and blank control total 6 treatments, each treatment repeated 3 times, repeated Wi...

Abstract

The invention relates to a botanical fungicide used for controlling the powdery mildew and gray mold of fruit trees and vegetables, in particular to a compounded fungicide containing zincpolyanemine and ethylicin, and pertains to the technical field of pesticides. The active ingredients of the fungicide are the zincpolyanemine and ethylicin with the weight ratio of 1:2 to 5:1. In the preparation ingredients of the fungicide, the ethylicin and the zincpolyanemine totally account for 5 percent to 60 percent of the weight of the preparation agents, grass vinegar accounts for 5 to 20 percent of the gross weight of the fungicide, addition agents (surfactant, wetter) account for 5 to 10 percent of the gross weight of the fungicide, and the rest is fillers. The invention utilizes the synergy of the zincpolyanemine and ethylicin to make up for the own deficiency of single-dosage pesticide, thus overcoming the pesticide resistance of diseases and improving the pesticide application effect. Through practical test, the fungicide has remarkable control efficiency to the powdery mildew and gray mold of fruit trees and vegetables, with high efficiency, safety and environment protection.

Description

technical field [0001] The invention belongs to the technical field of pesticides, and relates to a botanical fungicide for preventing and treating powdery mildew and gray mold of fruit trees and vegetables, in particular to a compound fungicide containing dark russin and acetoallicin. Background technique [0002] For strawberry, sand pear, grape, etc. in fruit trees, and tomato, pepper, etc. in vegetables, powdery mildew and gray mold are the main common diseases, and serious occurrences in some areas cause large yield losses. At present, in large-scale production, chemical control is still an important means to control the above two diseases. Since the main drugs used to prevent and treat the disease for many years are carbendazim, saccharin, triadimefon, etc., drug resistance has appeared in production; Shigao, polyoxin, Fuxing, and A Misida and other pesticides are mostly imported from abroad, and the price is high, which is difficult for farmers to accept in large-sca...
