Abstract

The present invention relates to a kind of pyrethrum dried pollen agent and its wettable powder, and its preparation method includes the following steps: pulverizing pyrethrum stem, leaf or dried flower, adding diatomite or talcum powder or clay whose added quantity is 10-30% of pyrethrum stem and leaf weight, mixing them uniformly, pulverizing and sieving with 200 meshes to obtain the pyrethrum pollen. According to the weight percentage of the above-mentioned pyrethrum powder 3-5% of TBHQ or BHT, 5-15% of gleditsia fruit or tea saponin, 1-3% of synergistic ether or octachlorodipropyl ether or synergistic amine are mixed, pulverized and sieved with 200 meshes, the above-mentioned pyrethrum pollen and all the auxiliary materials are mixed uniformly so as to obtain the invented wettable powder.

Description

Dry pyrethrum flower pulvis and wetting powder

Technical field

The present invention relates to the Dalmatian chrysanthemum product, specifically dry pyrethrum flower pulvis and wetting powder.

Background is propped up art

Existing pesticide powder and wetting powder are generally synthetic pesticide raw material pulverizing filled (talcum powder etc.) and are crushed to certain particle size, are used for the land for growing field crops insect protected; Perhaps again on the basis of powder pesticide guiding humid medium, stabilizing agent make wetting powder.Because of agricultural chemicals pulverizing back granularity proportion is lighter, because of causing medicinal powder, the air-flow effect drifts about everywhere during use, produce environmental pollution.

Summary of the invention

The purpose of this invention is to provide a kind of can the use with powder form, the drift of medicinal powder can not produce the agricultural chemicals that pollutes, i.e. dry pyrethrum flower pulvis and wetting powder to environment.

Technical scheme of the present invention is: dry pyrethrum flower pulvis and wetting powder prepare by the following method and get:

1) Dalmatian chrysanthemum cauline leaf or dried flower are crushed to the 80-100 order, behind the diatomite or talcum powder or clay mixing of the 10-30% of adding Dalmatian chrysanthemum cauline leaf weight, pulverized 200 mesh sieves again, get the Dalmatian chrysanthemum pulvis;

2) take by weighing TBHQ or the BHT of 3-5% by the percentage by weight of above-mentioned Dalmatian chrysanthemum pulvis, the Chinese honey locust of 5-15% or theine saponin, the Butacide of 1-3% or Octachlorodipropyl Ether or Octacide 264, with pulverizing 200 mesh sieves behind their mixings, standby;

3) Dalmatian chrysanthemum pulvis and above-mentioned standby comminuted material are stirred, get the Dalmatian chrysanthemum wetting powder.

Though Dalmatian chrysanthemum pulvis of the present invention and wetting powder also can drift about, but former powder is the Dalmatian chrysanthemum plant of pure natural, behind effective ingredient desinsection in crops surface or the ground, resolve into water and carbonic acid gas, remaining vegetable protein, vegetable fiber very soon, environment is not produced pollution.Pulvis is used to prevent and treat soil insect, and behind the desinsection, the vegetable fiber fermentation becomes fertilizer, and is extremely favourable to the growth of crops.

Dry pyrethrum flower pulvis of the present invention and wetting powder compared with prior art have following characteristics:

1, products material is easy to get, and quantity is big:

2, production and processing technology is simple, and cost is low, and product price is cheap;

3, easy to use, peasant household grasps using method easily;

4, the scope of application is wide, can be used for the insecticide of domestic hygiene, farmland, fruit tree, forest, vegetables, fruit, tealeaves etc.;

5, high-efficiency low-toxicity does not pollute the environment;

6, insect is difficult for developing immunity to drugs, and insecticidal spectrum is wide.

1) be prepared into the dry pyrethrum flower powder by the following method:

Dalmatian chrysanthemum cauline leaf or dried flower are crushed to 80 orders, add 15% diatomite mixing of Dalmatian chrysanthemum weight after, pulverized 200 mesh sieves again, the dry pyrethrum flower pulvis;

2) be prepared into the dry pyrethrum flower wetting powder by the following method:

A, by 1) in the percentage by weight of Dalmatian chrysanthemum pulvis take by weighing 3% TBHQ (antioxidant, trade name), 10% Chinese honey locust, 2% Butacide, with pulverizing 200 mesh sieves behind their mixings, standby;

B, Dalmatian chrysanthemum pulvis and above-mentioned standby comminuted material are stirred, the Dalmatian chrysanthemum wetting powder.

Embodiment 2:

1) be prepared into the dry pyrethrum flower powder by the following method:

The Dalmatian chrysanthemum cauline leaf is crushed to 80 orders, add 30% talcum powder mixing of Dalmatian chrysanthemum weight after, pulverized 200 mesh sieves again, the dry pyrethrum flower pulvis;

A, by 1) in the percentage by weight of Dalmatian chrysanthemum pulvis take by weighing 5% BHT (antioxidant, trade name), 15% theine saponin, 3% Octachlorodipropyl Ether, with pulverizing 200 mesh sieves behind their mixings, standby;

Claims

1, a kind of dry pyrethrum flower pulvis and wetting powder is characterized in that preparing by the following method and get:

1) Dalmatian chrysanthemum cauline leaf or dried flower are crushed to the 80-100 order, behind the diatomite or talcum powder or clay mixing of the 10-30% of adding Dalmatian chrysanthemum cauline leaf weight, pulverized the 200-mesh sieve again, get the Dalmatian chrysanthemum pulvis;
