Abstract

The invention discloses a composite germicide, which is prepared from the following components in parts by weight: 20-40 parts of sophora flavescens, 8-15 parts of calcium hypochlorite, 12-35 parts of folium eucalypti, 8-15 parts of copper sulfate, 15-30 parts of cortex meliae, 8-15 parts of cresol, 2-10 parts of quick lime, and 3-12 parts of sodium benzoate. According to the composite germicide disclosed by the invention, through preparing traditional Chinese medicine sterilization liquid from sophora flavescens, folium eucalypti and cortex meliae with bactericidal and insecticidal effects, compounding combined disinfection liquid prepared from calcium hypochlorite, copper sulfate and cresol, and also adding quick lime and calcium benzoate with an antiseptic effect, the prepared composite germicide is wide in bacteriocidal spectrum, good in sterilization effect and short in cycle, has no chemical residue, and has no pollution to the environment, and therefore, the composite germicide is applicable to the disease control of crops such as various vegetables and fruits.

Description

technical field [0001] The invention relates to the field of pesticides, in particular to a compound fungicide for vegetable and fruit crops. Background technique [0002] my country is a country dominated by agriculture. Some vegetables, melons and fruit crops with short growth period have many diseases and insect pests. In order to obtain a better harvest, more than 90% of the agricultural products have been sprayed to varying degrees during the production process. Various pesticides. Most of the applied pesticides contain toxic chemicals, and the common ones mainly include trichlorfon, omethoate, methyl parathion, fenitrothion, methamidophos and dichlorvos. The traditional pesticides used for sterilization and deworming have low efficacy and poor effect, which is specifically reflected in the fact that the amount of drugs actually used to kill diseases and insect pests only accounts for 10% to 20% of the application amount, and most of the rest of the pesticides are mostl...
