Problems solved by technology

[0007] Although there are many seed treatment agents on the market at present, the agents for rice seed treatment are basically concentrated on solving soil-borne diseases such as bakanae disease or dry apex nematode, etc., and control the main insect pests on rice-planthoppers and rice leaf rollers Foliar spraying is still the main method. During the rice growth period, multiple application of pesticides is required to effectively control the pest damage, which consumes a lot of manpower and material resources, and is easy to cause drug resistance of rice pests. The non-point source pollution of farmland is serious.

Embodiment 1

[0033] Preparation of 45% Chlorthialine · Chlorantraniliprole Suspension Seed Coating

[0034] formula:

[0035] 40% chlorothialine, 5% chlorantraniliprole, 7% polymer of polyvinyl acetate and polyvinyl alcohol, 1.5% ethylene glycol, 6% polyvinyl acetate, 4% polyethylene resin, xanthan gum 0.5%, organic silicones 0.5%, potassium benzoate 0.5%, basic rhodamine 1.5%, distilled water to make up the balance.

[0036] Preparation:

[0037] According to the above formula, chlorothialine and chlorantraniliprole were pulverized by airflow, and after the wetting and dispersing agent, film forming agent, colorant, thickener, antifreeze, preservative, defoamer and distilled water were completely dissolved, press The ratio is put into a sand mill and ground twice until the particle fineness of the suspension reaches D50 of 2 μm and D90<8 μm, and then 45% chlorthiazolin·chlorantraniliprole rice suspension seed coating agent can be prepared.

Embodiment 2

[0039] Preparation of 42% Chlorthialine · Chlorantraniliprole Suspension Seed Coating

[0040] formula:

[0041] 36% chlorothialine, 6% chlorantraniliprole, 7% polymer of polyvinyl acetate and polyvinyl alcohol, 1.5% ethylene glycol, 6% polyethylene acetate, 4% polyethylene resin, xanthan gum 0.5%, organic silicones 0.5%, potassium benzoate 0.5%, basic rhodamine 1.5%, distilled water to make up the balance.

[0042] Preparation:

[0043] According to the above formula, chlorothialine and chlorantraniliprole were pulverized by airflow, and after the wetting and dispersing agent, film forming agent, colorant, thickener, antifreeze, preservative, defoamer and distilled water were completely dissolved, press The ratio is put into a sand mill and ground twice until the particle fineness of the suspension reaches D50 of 3 μm and D90<7 μm, and then 42% chlorthiazolin·chlorantraniliprole rice suspension seed coating agent can be prepared.

Embodiment 3

[0045] Preparation of 40% Chlorthialine · Chlorantraniliprole Suspension Seed Coating

[0046] formula:

[0047] 32% chlorothialine, 8% chlorantraniliprole, 7% polymer of polyvinyl acetate and polyvinyl alcohol, 1.5% ethylene glycol, 6% polyvinyl acetate, 4% polyethylene resin, xanthan gum 0.5%, organic silicones 0.5%, potassium benzoate 0.5%, basic rhodamine 1.5%, distilled water to make up the balance.

[0048] Preparation:

[0049] According to the above formula, chlorothialine and chlorantraniliprole were pulverized by airflow, and after the wetting and dispersing agent, film forming agent, colorant, thickener, antifreeze, preservative, defoamer and distilled water were completely dissolved, press The ratio is put into a sand mill and ground twice until the particle fineness of the suspension reaches D50 of 2.5 μm and D90<6 μm, and then 40% chlorthiazolin·chlorantraniliprole rice suspension seed coating agent can be prepared.

Abstract

The invention discloses a rice suspension seed coating agent containing imidaclothiz and chlorantraniliprole. The rice suspension seed coating agent is characterized by mainly comprising main components, auxiliary agents and distilled water; the main components comprise the imidaclothiz and the chlorantraniliprole, wherein the imidaclothiz accounts for 10 to 40 mass percent of the rice suspension seed coating agent, and the chlorantraniliprole accounts for 2 to 10 mass percent of the rice suspension seed coating agent; the invention also discloses application of the rice suspension seed coating agent containing the imidaclothiz and the chlorantraniliprole; the rice suspension seed coating agent disclosed by the invention can effectively control the outbreak of laodelphax striatellus through one-time seed treatment in a seedling stage, and has a good prevention and control effect on stenchaetothrips biformis; through one-time seed treatment, cnaphalocrocis medinalis guenee in the early and medium stages of rice can be controlled basically, and the cnaphalocrocis medinalis guenee is basically not required to be prevented and controlled until the rupturing stage of the rice; the using amount and the using frequency of pesticides are obviously reduced, so that the prevention and control cost is reduced, much labour is saved, meanwhile, the environmental pollution is reduced, and pesticide residues of agricultural products are reduced; therefore, the rice suspension seed coating agent containing the imidaclothiz and the chlorantraniliprole can be widely applied to the field of rice seed treatment.

Description

technical field [0001] The invention relates to the prevention and control of rice pests, in particular to a rice suspension seed coating agent containing chlorothialine and chlorantraniliprole and an application thereof. Background technique [0002] In modern agricultural production, the use of seed coating agents to treat seeds is one of the most economical and convenient methods to prevent and control underground pests and crop soil-borne and seed-borne diseases. A seed coating is a pesticide formulation used for the treatment of crop or other plant seeds with film-forming properties that solidify on the surface of the seed to form a film called a seed coat. The seed coating agent absorbs water and swells in the soil without being dissolved, allowing the water and air required for normal germination of the seeds to pass through, and the contained pesticides and seed fertilizers are slowly released, which can kill underground pests and seedling pests, and has the function...
