Composite natural insecticide for preventing and controlling red spiders and preparation method of composite natural insecticide

Abstract

The invention discloses a composite natural insecticide for preventing and controlling red spiders and a preparation method of the composite natural insecticide. The composite natural insecticide comprises the following components in parts by weight: 50 to 80 parts of tomatoes, 30 to 50 parts of garlic, 20 to 40 parts of green Chinese onion, 20 to 40 parts of onion, 5 to 10 parts of ginger, 5 to 10 parts of Chinese prickly ash and 1 to 3 parts of soap. The preparation method comprises the following steps of (1) weighing the Chinese prickly ash in proportion, adding water, heating to be in a slightly boil state, keeping the slightly boil state for 3 to 4 hours, standing, cooling and filtering, so as to obtain a filter liquor I for standby application; (2) weighing the tomatoes, the garlic, the green Chinese onion, the onion and the ginger in proportion, mashing, adding the filter liquor I prepared in the step (1), soaking for more than 24 hours, filtering, adding the soap and stirring to completely dissolve, so as to obtain a raw liquor of the composite natural insecticide. Raw materials of the composite natural insecticide are natural and environmental, and after being applied, the composite natural insecticide is harmless to human bodies and environments; the composite natural insecticide has a relatively strong tagging effect on the red spiders and has the advantages of good effect and no resistance; the preparation method has the advantages of simplicity and easiness in raw material obtaining and is suitable for industrial production.

Description

technical field [0001] The invention belongs to the technical field of pesticide production, and in particular relates to a compound natural insecticide for preventing and controlling spider mites and a preparation method thereof. Background technique [0002] In the cultivation process of flowers, spider mites have become the most common destroyers, including rose, Milan, jasmine, kumquat, crabapple, osmanthus, bergamot and other flowers. The spider mites are very small, less than 1mm, so they are not easy to be found. By the time the damage is noticed, the plants have already been seriously damaged. It mainly absorbs the juice of plants, causing a large loss of chlorophyll in plants, reducing water, grayish yellow spots or plaques on leaves, and soon leaves will turn yellow and fall off, and red spiders can also spread viruses. In addition, the red spider's reproductive ability is also super strong. It can reproduce one generation in a week, and both sexes and parthenogen...

Problems solved by technology

[0003] There are many ways to prevent and control spider mites. Firstly, according to the high-temperature-resistant living habits of spider mites, plants can be watered more and the temperature of the crop environment can be lowered. However, this method has high limitations and is not suitable for all plants. In addition, it can also be controlled by cultivating natural enemies. There are many natural enemies of red spider mite, such as deep-pointed ladybug, tube-eating ladybug, heterochromia ladybug, large and small lacewings, small flower bugs, Phytoseiid mites, etc. This method is the most natural and environmentally friendly, but it will also cause other pest hazards; the most common method for people is to use chemical pesticides to prevent and control. At present, the chemical pesticides used to prevent and control red spiders include 10% pyridaben EC 1000 times of liquid, 1000 times of 10% pyridaben EC, 3000 times of 5.7% emamectin emamectin emulsifiable concentrate, although the control effect of chemical pesticides is very good, its toxic effect on the human body cannot be ignored; there is also a kind of control The method is to use natural plants to prevent and control, such as rotenone, tobacco, Datura, etc., but these plants have limited sources, high production costs, and limited effects when used alone, and it is difficult to maintain long-term drug effects
