Problems solved by technology

In addition, the random discarding of a large number of agricultural wastes today has not only caused a lot of resources to be idle and wasted, but also caused a certain burden on the environment. Therefore, to realize the recycling of agricultural waste resources and fully utilize the idle resources Some social and economic value, to achieve sustainable development has become the direction of today's agricultural development

Embodiment 1

[0026] Compound plant fungicide composed of 80% raw material and 20% conventional excipients

[0027] Weigh the discarded stems, leaves, flowers, fruits or their mixture when camphor is pruned or naturally shed, and the discarded stems, leaves or roots of tomato after pruning or harvesting, the stems, leaves or roots of quinoa, and the stems of Solanum nigrum 100g (wherein Cinnamomum camphora accounts for 40%, tomato 5%, small quinoa 25%, Solanum nigrum 30%), the powder (20 mesh particles) of leaf or root is totally 100g, with 70% ethanol solution 500ml soaking 2d at room temperature, filter, The filtrates of the four plants are concentrated under reduced pressure to recover the solvent to obtain the extract, and then Tween, which accounts for 20% by weight of the whole compound plant fungicide, is added, stirred according to the conventional process, and mixed evenly to prepare the compound plant fungicide. Then it is diluted with water to be prepared as a compound plant fung...

Abstract

The invention discloses a compound plant bactericide, a preparation thereof and application. The bactericide is composed of, by weight, 40-80% of raw material chemicals and 20%-60% of conventional auxiliary materials. The raw material chemicals comprise the components including, by weight, 5-40% of cinnamomum camphora extract, 5-40% of tomato extract, 2-30% of chenopodium serotinum extract and 2-30% of solanum nigrum extract. The compound plant bactericide is efficient, free of residue, low in production cost, economical, practical, environment-friendly and good in combination property, adopts agricultural wastes, has no environmental pollution problems, and is a pollution-free, botanical and biological pesticide.

Description

technical field [0001] The invention relates to a plant fungicide in the technical field of pesticides, in particular to a compound plant fungicide containing camphor and its preparation and application. Background technique [0002] Pesticides play an important role in controlling agricultural pests and increasing agricultural production and income. In order to improve the quality of human living environment and food quality, countries all over the world are conducting research on reducing the amount of chemical pesticides. Pollution, high biological activity, high selectivity biological pesticide. Among them, finding substances with antibacterial activity from plants has become an important way to create new fungicides. In addition, the random discarding of a large number of agricultural wastes today not only causes a lot of resources to be idle and wasted, but also causes a certain burden on the environment. Therefore, to realize the recycling of agricultural waste reso...
