Embodiment 1

[0013] Take 100kg of Chaku with an oil content below 5%, put it into water together with 30kg of wild cotton roots or immature wild cotton fruits, and cook at 100-120°C for 60 minutes, the weight ratio of material and water is 1:3 ~5. Then put the mixed slag liquid into 500 kg of water, soak for 30 minutes, and filter to obtain the liquid insecticide. The method of use is to mix the insecticide with water, the weight ratio of the potion is 1:1~1.5, spray at around 10:00 in the morning, and spray again after 20 days, and the dosage after mixing with water is 20 kg / mu / Second-rate. It does no harm to seedlings, vegetables, fruit trees and other crops, and kills 98% of pests. The environmentally friendly insecticide is sealed and sealed, and has a shelf life of 90 days.

Embodiment 2

[0015] Mix 100 kg of Cha Kut with an oil content of less than 5% and 40 kg of immature wild cotton fruit, boil in water for 60 minutes, the weight ratio of material and water is 1:3~5, and the temperature is 100~120°C. The filtrate is mixed with 100 kilograms of water, and 1 kilogram of sodium chloride is added, and the mixture can be used after mixing. The method of use is the same as in Example 1. After the obtained filter residue is pulverized, add 1 kg of sodium chloride and 100 kg of water, and it can also be used as an insecticide.

Embodiment 3

[0017] Take 50 kg of tea leaves, 5 kg of wild cotton roots, 5 kg of tobacco stems, 2.5 kg of willow leaves, 2.5 kg of red peppers, 1 kg of asarum, 0.25 kg of pinellia, 5 kg of lime water (lime saturated aqueous solution at room temperature), 2.5 kg of plant ash and 0.5 kg of tung tree seed shell ash are mixed and boiled with water for 60 minutes. The weight ratio of material and water is 1:3~5, and the temperature is 100~120°C. The liquid insecticide can be obtained by filtering, and the filter residue is a good organic fertilizer. The method of use is the same as in Example 1. The insecticidal effect is evident within 20 minutes, and the pest killing rate is over 98%. The shelf life of the insecticide is 6 months.

Abstract

The invention provides camellia environment-friendly insecticide, which is formed by compounding seed residue of the camellia with the oil content lower than 5 percent with ingredients, wherein the weight ratio of the seed residue to the ingredients is 10:2-5, and the ingredients comprise anemone vitifolia fruits or roots. A method for preparing the insecticide comprises the steps of mixing the seed residue with the ingredients, boiling the mixture for 60 minutes at a temperature of between 100 and 120 DEG C, ensuring that the adding amount of water is 3 to 5 times the weight of the mixture of the seed residue and the ingredients, cooling and filtering the obtained product. The insecticide has killing effects on moth larvae, leaf roller moths, leafhoppers, core roller moths, plant aphids, ants, white flies, red spiders, rice planthoppers and other pests on fruit trees, vegetables, seedlings and other crops, and reaches the killing rate over 98 percent. The insecticide has the advantages of validity period as long as more than 20 days, no harm to crops, little environmental pollution, little drug residue, low production cost, simple preparation method and safe convenient use.

Description

technical field [0001] The present invention relates to an insecticide, in particular, provides an insecticide mainly prepared from oil tea extract. Background technique [0002] There are many kinds of existing insecticides, but most of them are chemical insecticides. Since chemical insecticides are easy to make harmful insects immune, the amount of insecticides needs to be continuously increased, which not only affects the insecticidal effect, but also increases cost of pest control. In particular, chemical pesticides remain on crops, soil and water, posing a threat to human health and polluting the environment. [0003] Camellia oleifera has been reported as a research on the use of insecticides, mainly extracting active ingredients from camellia oleifera to prepare insecticides. For example, tea saponin extracted from camellia oleifera is exactly a kind of preparation raw material of insecticides. A "biological insecticide extracted from camellia oil" (200510012084.1) ...
