Problems solved by technology

When insects are seen, pesticides are applied, and the number of sprayings increases correspondingly, resulting in high cost of prevention, and at the same time increases the resistance of aphids, further increasing the difficulty of control; if the control is too late, aphids have already caused certain damage to wheat, and the density of aphids is too large. If the pesticide cannot be applied evenly, the damage of aphids cannot be effectively controlled.
[0004] Moreover, most farmers are anti-targeted when choosing pesticides, mistakenly believing that pesticides with high toxicity are relatively effective in killing insects
Highly toxic and poisonous pesticides are generally broad-spectrum insecticides. While effectively controlling target pests, they will also harm natural enemies and some beneficial organisms such as bees, thereby destroying the balance of the entire farmland ecosystem. Pollution of water bodies and ecological environment
At the same time, the duration and residue of highly toxic pesticides are high, and the application of pesticides near the harvest period will cause excessive pesticide residues in grains, which is not conducive to the healthy life of the people

preparation example Construction

[0055] The present invention also provides a preparation method of the slow-release medicinal fertilizer, comprising: A) mixing and granulating the pesticide composition, fertilizer, auxiliary agent, slow-release material and filler to obtain the slow-release medicinal fertilizer.

[0056] The present invention has no special limitation on the sources of all raw materials, which can be commercially available. Wherein, the pesticide composition, fertilizer, adjuvant, slow-release material and filler are all the same as above, and will not be repeated here.

[0057] According to the present invention, it is preferable to first mix and granulate part of the pesticide composition, fertilizer and auxiliary agent, more preferably first to mix and granulate the amino oligosaccharin, humic acid, part of thiamethoxam, fertilizer and auxiliary agent in the agricultural chemical composition . The mixing is preferably carried out in a disc granulator. After the above-mentioned raw materi...

Embodiment 1

[0064] Mix thiamethoxam, amino oligosaccharides and humic acid for an indoor joint independent test experiment, use the nitrogen base of thiamethoxam, amino oligosaccharides and humic acid as the control agent, and mix the pesticide composition according to the following ratio 1~pesticide composition 5:

[0065] Pesticide composition 1: thiamethoxam: oligosaccharin: humic acid = 1:5:10;

[0066] Pesticide composition 2: thiamethoxam: amino oligosaccharin: humic acid = 1:2:10;

[0067] Pesticide composition 3: thiamethoxam: amino oligosaccharin: humic acid = 1:1:5;

[0068] Pesticide composition 4: thiamethoxam: amino oligosaccharin: humic acid = 5:8:10;

[0069] Pesticide composition 5: thiamethoxam: amino oligosaccharin: humic acid = 1:1:3.

[0070] In the experiment, wheat aphids were used as the test insects, and a blank control was set up. The single agent of thiamethoxam, amino-oligosaccharin and humic acid, and the above five pesticide compositions were used to soak i...

Embodiment 2

[0076] Pesticide composition: thiamethoxam 0.02%, amino oligosaccharin 0.1%, humic acid 0.2%;

[0077] Fertilizer: nitrogen content 20%, phosphorus content 15%, potassium content 10%, calcium content 0.1%, magnesium content 0.3%, zinc content 0.01%, boron content 0.01%, molybdenum content 0.01%;

[0078] Additives: stearic acid 1%;

[0079] Sustained release material: polyvinyl alcohol 1.5%;

[0080] Filler: supplemented to 100%, the filler is a mixture of attapulgite, bentonite and gelatinized starch.

[0081] According to the above ratio, put the amino oligosaccharidins, humic acid, fertilizer and additives into a disc granulator to pulverize, mix evenly, and the obtained mixture is the granule intermediate; Spray the pre-prepared 40% thiamethoxam oil suspension solution in the middle of the granules, and sprinkle the slow-release materials and fillers in the middle of the granules while spraying. After the granulation is completed, roll in the disc for 20 minutes, dry, cool...

Abstract

The invention provides a pesticide composition, slow release pesticide fertilizer and a preparing method of the slow release pesticide fertilizer. The slow release pesticide fertilizer comprises fertilizer, slow release materials, an assistant, filler and the pesticide composition. The medicine composition comprises thiamethoxam, amidogen oligosaccharide and humic acid. Compared with the prior art, after thiamethoxam, amidogen oligosaccharide and humic acid are compounded for the slow release pesticide fertilizer, the toxicology of thiamethoxam, amidogen oligosaccharide and humic acid is larger than 120, and the obvious synergism is achieved; according to the slow release pesticide fertilizer, the pesticide composition and the fertilizer are compounded, the effects that activity is high, the pesticide effect is good, the fertilizer efficiency is obvious and the effects of pesticide and fertilizer are obtained are achieved, and the functions of insecticide, bacteriostat and fertilizer increasing can be brought into full play; the slow release technology is adopted, scientific releasing of pesticide and fertilizer is effectively guaranteed, and the double effects of pesticide and fertilizer are ensured; the lasting period of products is prolonged, and the pesticide efficiency and the utilization rate of pesticide are improved; waste of pesticide and fertilizer is reduced, and the resistance development of wheat aphids on pesticide can be relieved.

Description

technical field [0001] The invention belongs to the technical field of pesticides, and in particular relates to a pesticide composition, a slow-release medicinal fertilizer and a preparation method thereof. Background technique [0002] The wheat aphid is the largest and most harmful pest of wheat perennial. It is one of the important pests of wheat in my country. Wheat aphids are small and reproduce quickly, and can occur throughout the wheat growth period. They are also one of the main pests in the late growth period of wheat. They cause damage to wheat, affect wheat photosynthesis, nutrient absorption and conduction, and harm leaves, stems and For young ears, especially after wheat heading, the temperature rises and the aphids reproduce faster, concentrating on the ears and forming grains. If the control is not timely, the thousand-grain weight will drop seriously, and the yield will generally be reduced by 10% to 30%. Nymphs and adults often gather in large numbers on l...
