Description

Non-toxic biodegradable insecticide

technical field

The present invention relates to an insecticide made by mixing fertilizers with polyglucoside.

Background technique

Whiteflies exhibit early immunity to synthetic insecticides. By the 1980s, they had become serious greenhouse pests. The pest not only eats the plant, but excretes a nectar that mars the plant's appearance, attracts other insects, and produces smoke mold. Whiteflies also transmit plant viruses. Consumers refuse to buy products infested with whiteflies. There are several species of whiteflies that infest greenhouse plants, and they usually have large host populations and are resistant to insecticides. Greenhouse tomatoes and poinsettia were the hardest hit varieties. The most common whiteflies in greenhouses are: greenhouse whitefly (Trialeurodes vaporariorum), sweet potato whitefly (Bemisia tabaci) and silver foil whitefly (Bemisia argentifolii).

There are many types of pesticides. One downside of chemical insecticides is that offspring of the insects can develop resistance. In addition, chemical pesticides will remain in food and water, which is harmful to animals and people.

Contents of the invention

The invention provides a non-toxic and biodegradable insecticide, which is very effective for killing soft-bodied insects, has no residue on plants, has high insecticidal efficiency, long-term effect, is easy to operate, easy to manufacture and easy to apply, and is easy to use. Safe and non-polluting to the environment. For this reason, the present invention is a mixture of water-diluted phosphate and polyglucoside. Described phosphate is potassium dihydrogen phosphate. The polyglucoside in the mixed solution is short-chain aliphatic alcohol and glucose. The polyglucoside is C8-C10 alkyl polyglucoside. The concentration of potassium dihydrogen phosphate in the mixed solution is 5%-15%. The polyglucoside concentration in the mixed liquid is 10%-35%. The mixed liquid contains, by weight percentage: 30-35% of C8-C10 alkyl polyglucoside, 5-10% of potassium dihydrogen phosphate, and 58-62% of water. In the use solution prepared from the mixed solution, the concentration of potassium dihydrogen phosphate is 0.01%-0.03%, and the concentration of C8-C10 alkyl polyglucoside is 0.02%-0.06%. The concentration of the liquid for use in the mixed liquid is 0.2%-0.5%.

The polyglucoside and potassium dihydrogen phosphate mentioned in the above ingredients of the present invention are all materials purchased in the market, wherein the production plant of polyglucoside and C8-C10 alkyl polyglucoside is Henkel, Germany. C8-C10 alkyl polyglucoside is used as an auxiliary pesticide in agriculture, which meets the requirements of environmental protection agriculture, and is allowed to be used in the horticultural circles of the United States and Europe. Potassium dihydrogen phosphate is used in water-soluble fertilizers.

The invention is environmentally friendly, degradable, has high insecticidal efficiency, long-term effect, easy operation and release, safe use, and no adverse effects on human body and environment during the manufacturing process and after use. The invention can kill acarid insects, crickets, aphids, ants, especially whitefly. The invention has been shown to be very effective against soft-bodied insects such as: aphids, leafhoppers, water worms, thrips, spider mites and whiteflies. And leaves no residue on plants.

The solution of the present invention is used after being diluted in water at a rate of 1:200.

The results of killing whitefly adults and larvae:

As a comparison, the following substances with different components were added to the mixture used together with fertilizer (phosphate). Experiments were carried out in different greenhouses using standard sprinklers. mortality rate% Adult larva A Silicon polymer 53 45 B Nonylphenol polyglycol ether NP6 64 43 C Ethoxyethanol (Sec alcohol ethoxylate HLB 10,5) 58 46 D.

Conclusion: C8-C10 polyglucoside is the most effective in the mixed solution.
