Pollution-free special pesticide for broccoli

Abstract

The invention discloses pollution-free special pesticide for broccoli. The pollution-free special pesticide is prepared from the following substances: serissa serissoide, pericarpium zanthoxyli, golden cypress, melia azedarach leaves, menthe leaves, grape seeds, radix polygalae, radix sanguisorbae, chrysanthemum leaves, modified attapulgite and modified bentonite. Traditional Chinese medicine extracting liquid, the modified bentonite and the modified attapulgite are compounded to obtain finished-product pesticide; all the components interact, so that the pollution-free special pesticide has a very good healing effect on common downy mildew, soft rot, damping off, sclerotinia stem rot and the like of the broccoli; the healing rate reaches up to 97.5 percent or more and the diseases do not easily recur; drug resistance is not easy to generate and the stability of the pesticide is better; beneficial components are not easy to decompose and the quality guarantee period can be prolonged to be about three times; after the pollution-free special pesticide is applied, growth properties of broccoli plants are improved better; the content of flavonoids in the cultured broccolis is improved by 30 percent to 40 percent and the content of iron and zinc elements is improved by 10 percent to 20 percent, so that the broccoli has very good edible value.

Description

technical field [0001] The invention belongs to the field of pesticides, in particular to a special pesticide for pollution-free broccoli. Background technique [0002] Broccoli is a one-year-old herbaceous plant, which originates in the eastern coastal areas of the Mediterranean Sea and is cultivated in many areas of my country. Broccoli is rich in nutrition, containing protein, sugar, fat, vitamins and carotene. Its nutritional content ranks first among similar vegetables. It is known as the "vegetable crown" and is one of the more common vegetables on the modern people's table. [0003] There are many kinds of plant diseases and they are distributed in a wide area. They often cause very serious harm to agricultural production, ranging from reduced production to severe crop failure. Pesticides are important materials to ensure high agricultural yields. Although chemically synthesized pesticides have played a huge role in controlling and eliminating various plant diseases ...

Problems solved by technology

[0005] Now people try to prepare a variety of botanical pesticides to prevent and control plant diseases and insect pests, but there are common problems such as easy decomposition of active ingredients, limited duration of action, and short shelf life. Some people try to add white carbon black, light calcium, attapulgite Pesticide carriers such as soil and bentonite can be used to improve such problems, but most of the above-mentioned pesticide carriers have problems such as high surface acid value (pKa<1.8) and strong water absorption capacity (up to 15%), and the effect on pesticide promotion is not obvious
