Description
Technical field
The present invention relates to technical field of pesticide preparations, and in particular to a kind of pesticide powder and preparation method thereof.
Background technique
Also need to use pesticide in agriculture field, pesticide refers to for preventing, eliminating or controlling harm agricultural, forestry
Disease, worm, grass and the chemical substance of other harmful organisms, and the synthetics of plant, insect growth are purposefully adjusted, this
A little substances are mainly derived from biology, a kind of substance of other natural materials or the mixture and its preparation of several substances.In agriculture
In industry production, pesticide can ensure, promote the growth of plant and crops, eliminate pest, sterilization, kill harmful animal etc..It kills
It include a kind of internal-suction type drug in worm agent, this insecticides is absorbed by vegetable seeds, root, stem, leaf and transporting is to complete stool, one
In the timing phase, with substance or its activated metabolite with pests plant tissue or suck water and enter polypide, rise poison
The effect of killing.Internal-suction type insecticide hides that the phase is long, and the insect prevention deinsectization for being highly suitable for the non-consumption crop such as flowers, nursery stock makes
With.
However, the defect of traditional formulations of pesticide nature results in after being administered to farmland, infiltration, evaporation, drop will receive
The effect of solution causes the waste of resource.Wherein powder pesticide is easily blown off or is rushed by rainwater then since blade face adhesion is poor
Brush, drug effect phase are shorter.The effective rate of utilization of traditional pesticide only has 20%-30%, and lasting period, release characteristics etc. all cannot
Meet crop demand, and increases agriculture production cost.
It is prepared into that spherical, hollow scrotiform etc. is different to be tied by being wrapped up using slow-release material, being coupled, inlay etc. pesticide
When the dosage form of structure, wall material can provide physical barrier effect, thus can block ultraviolet light, significantly improve the light durability of pesticide,
The absorption for reducing soil delays degradation caused by illumination or other undesirable elements, decomposes and be lost, while can reduce toxicity,
Pollution abatement improves the control efficiency of product.Such dosage form also have the function of control release, according to application scene difference,
Slow-release and quick releasing type can be divided into.It therefore is the dosage form of one kind needed for existing market with the pesticide powder of slow-release function.
A kind of pesticide powder is disclosed in Chinese patent application 201710383921.4 (applying date: on May 26th, 2017),
By sapropel, adhesive agent, anti-drift agent, alachlor, jinggangmeisu, tetramethyl thiuram disulfide, vinifera slag, hexadecane
The raw materials such as base ammonium bromide, ethyl orthosilicate are made, and pesticide powder of the present invention is easy to use, are not required to be watered, particularly suitable in arid
The mountain area of water shortage uses, and under the premise of ensure that high drug load, increases the blade face adhesion of pulvis, more conventional pulvis agriculture
Medicine can play the more long-acting drug effect phase.But the pesticide activity component of the pesticide powder is still remained without release coated processing
The problems such as pesticide efficacy is low, the duration is short, it is difficult to the demand of crop.

Performance test
Using orchid as the sample of planting experiment, the insecticidal effect of pesticide powder in the present embodiment and comparative example is tested, point
Not using red spider, aphid and scale insect as statistics insect pest type, the vermins-proof effect of each group sample, vermins-proof effect statistics are counted
In, it does not find that pest is denoted as "○", finds but do not cause insect pest to be denoted as " △ " plant, infection insect pest is denoted as "×"；And it counts
The drug effect duration of each group sample, obtain following test result:
Table 1: the vermins-proof effect statistics of the orchid of each group embodiment in the present embodiment
It analyzes above-mentioned test result to find, the drug of the present embodiment and comparative example all has protection effect to most of insect pest
Fruit, blank control group are more serious due to the problem of not applying drug, infecting insect pest.By the present embodiment 1-3 and comparative example
1-3 has found that the drug effect phase of pesticide powder provided by the invention is obviously prolonged after comparing, have stablize lasting drug latentiation phase and
Duration.
The foregoing is only a preferred embodiment of the present invention, is not intended to restrict the invention, although referring to aforementioned reality
