Problems solved by technology

③ Workers and staff who produce pesticides are prone to pesticide poisoning and occupational diseases, and are also likely to cause poisoning to those who use chemical pesticides
④Chemical pesticides pollute the land. Since most chemical pesticides grow stably and are not easy to decompose, they will accumulate slowly and form a public nuisance
⑤Chemical pesticides are very toxic. After using chemical pesticides, the world that eats insects, such as birds and beneficial insects, will also be killed or poisoned, and it will destroy the biological chain of nature
⑥ The agricultural products produced contain pesticide residues, which are harmful to human health
⑦It is very inconvenient to store and transport chemical pesticides
⑧During the long-term use of chemical pesticides, the killed insects tend to develop drug resistance and resistance. After a long time of use, there will be pests that cannot be eliminated under low concentration conditions

Embodiment 1

[0075] 1. Example location: Yuhuangmiao Town, Shanghe County, Jinan City, Shandong Province

[0076] 2. Example plant: cotton

[0077] 3. Example area: 6.2 mu

[0078] 4. Implementation time: June 3, 2017 - July 31, 2017

[0079] 5. Pest situation of the embodiment: On June 3, the staff went to the cotton field to check, and the cotton cutworm was severely infested by the cutworm. The cutworm bit off a lot of cotton seedlings, cotton twigs, and bit the cotton leaves, which had caused part of the cotton Broken ridges and lack of meows. Many insects with a length of 16-22 mm were found on site. The on-site personnel confirmed that they were typical cutworm pests.

[0080] 6. Embodiment method:

[0081] On the afternoon of June 3, spray this product directly on the ground surface and cotton seedlings with a dry powder sprayer. By the morning of June 4, when the insecticidal effect was checked, most cutworms had died. By June 19 , when checking, there are still a small number ...

Embodiment 2

[0085] 1. Example location: Rose Town, Pingyin County, Jinan City, Shandong Province

[0086]2. Example plant: corn

[0087] 3. Example area: 10.2 mu

[0088] 4. Implementation time: June 28-July 25, 2018

[0089] 5. Insect damage in the example: On June 28, the staff inspected the cornfield of Ms. Qi Chunmei in Rose Town. There were needleworm pests in the cornfield. The insects killed the dry, and found that the needleworms were hiding in the lower part of the corn leaves, the lower part of the weeds, and the cracks on the surface of the corn, and the insect damage was very serious.

[0090] 6. Instance methods

[0091] On the afternoon of June 28 for the first time, add 40 kg of water to 1 kg of this product, and spray it on the ground and corn seedlings with a sprayer. When checking in the morning of June 29, it was found that many needleworms had been killed.

[0092] On the afternoon of July 1st, this product was used to spray this product on the ground surface and ...

Embodiment 3

[0095] 1. Example location: Baizhuang Village, Xiaobai Town, Pingyin County, Jinan City, Shandong Province

[0096] 2. Example plant: Potato

[0097] 3. Example area: 4.2 mu

[0098] 4. Implementation time: June 24-July 15, 2018

[0099] 5. Insect pest situation in the embodiment: on June 24, 2018, the staff and farmers checked in the potato field, and dug up the surface soil layer, and there were serious grub pests. According to the five-point method, the soil layer was excavated, and the excavation pit was inspected. 3 grubs were dug out at one point, some 6 grubs were dug out, and an average of 4 grubs were dug out from each pit. The potato seedlings were observed respectively, and 3-4% of the potato seedlings were bitten off by the grubs. The inspectors judged that this was a serious grub pests.

[0100] 6. The scheme of the embodiment to eliminate grubs: at 5 o'clock in the afternoon on June 24, directly spray this product in the potato field with a dry powder sprayer,...

Abstract

The invention discloses a powder insecticide processed by biomass materials and a preparation method thereof, and belongs to the technical field of insecticide preparation. The powder insecticide is prepared from the following raw materials: radix sophorae flavescentis, datura stramonium seeds, caulis erycibes, Chinese coriaria roots, radix et rhizoma nardostachyos, semen strychni, radix euphorbiae ebractealatae, balansa arisaema rhizome, herba euphorbiae royleanae, radix aconiti feri, super dampproofing agents, bulking agents and anti-blocking agents. An ultrasound extraction technology is used for extracting toxic ingredients in plants, i.e., the toxic ingredients in the plants are concentrated; the concentrated ingredients can effectively kill large insect bodies; exactly, large insectscan be effectively killed by improving the concentration of the concentrated ingredients. When the powder insecticide is used, the crop yield increase is obvious; the yield increase range is 8.78 to24.6 percent; the death rate is 95 to 98.75 percent; the correction death rate reaches 89.19 to 97.37 percent; the economic benefits are obvious.

Description

technical field [0001] The invention belongs to the technical field of insecticide preparation, relates to agriculture and forestry industries, and in particular to a powder insecticide that uses biomass raw materials to produce and eliminate large underground pests grubs, cutworms, needleworms, and onion maggots, and a preparation method thereof . Background technique [0002] At present, chemically synthesized highly toxic pesticides are used to control large-scale pests internationally. The following are the current methods for killing grubs, cutworms, needleworms, and onion maggots. [0003] The use of chemical pesticides to kill grubs mainly uses 50% phoxim, 20% methylisothion powder and 20% parathion for control. The use of chemical pesticides to kill cutworms mainly uses 50% methamidophos, 80% trichlorfon and 50% phoxim for control. For the use of chemical pesticides to kill golden needleworms, 50% phoxim, 2% methylisothion powder and chemical pesticides such as met...
