Problems solved by technology

[0003] At present, my country is in the stage of rapid development of cooperative organizations such as large grain growers, and the area of ​​industrialized cultivation such as rice seedlings is increasing rapidly. However, the pesticides used in the rice seedling stage are mainly used to prevent pests or diseases alone, and there are few products that can control diseases and pests at the same time. And lepidopteran pests have also developed resistance to pesticides that have been maturely used

Embodiment 1

[0028] Example 1 (20% Tebuconazole·Cyanraniliprole suspending agent)

[0029] Tebuconazole 5%, cyantraniliprole 15%, phosphate dispersant (FS3000) 4%, sulfonate wetting agent (SXC) 1%, magnesium aluminum silicate 1%, xanthan gum 0.1%, Silicone defoamer 0.3%, ethylene glycol 5%, and the balance is deionized water. The above formula is pre-pulverized in proportion, then added to a sand mill for grinding, and mixed with high shear to prepare a 20% A·cyhalothrican suspending agent.

[0030] This embodiment is applied to the control of rice borer and blight at the seedling stage of rice. 20% Tebuconazole·Cyaniliprole suspension concentrate according to the active ingredient 5g / mu in the peak period of the hatching larvae of Diplodocus chinensis, and the initial stage of blight, and spray evenly with water. , the control effects of blight were 87.9-97.8%, 78..2-87.4%, respectively. According to the same method, control a single dose of 30% A water agent (the application rate is 1...

Embodiment 2

[0031] Example 2 (15% pyraclostrobin·chlorofluranilide suspension seed coating agent)

[0032]1.0% pyraclostrobin, 14.0% chlorfluranilamide, 1.0% film-forming agent PVA, 1.0% NP-101, 3.0% polyoxyethylene ether phosphate, 5.0% ethylene glycol, 0.01% BIT, silicone Defoamer 0.3%, xanthan gum 0.1%, vigilant rhododendron 1.5%, and the rest is water. The above formula is pre-pulverized in proportion, and then added to a sand mill for grinding. After high-shear mixing, a film-forming agent and a warning tone are added to prepare a 15% A·cyhalothraniliprole suspension seed coating agent.

[0033] This embodiment is applied to control rice borer and rice blast. 15% Pyraclostrobin·Cyaniliprole suspension seed coating is treated with rice seed dressing according to the active ingredient 10g / 100kg of seeds, and the seedlings are raised normally. The control effect of the rice borer and rice blast 30 days after the treatment They were 87.5-99.5% and 76.8-88.4% respectively. Seed dressin...

Embodiment 3

[0034] Example 3 (50% Jinggangmycin·Cyaniliprole water dispersible granules)

[0035] According to Jinggangmycin 10.0%, cyanuridine 40%, dispersant (NNO + sodium lignin) 5%, pull powder BX3%, K-12 (sodium lauryl sulfate) 4%, binder carboxymethyl Base (ethyl) cellulose 5%, disintegrant (glucose) 5%, diatomaceous earth 3%, kaolin clay supplemented to 100%. According to the requirements of the formula, mix the original drug, dispersing agent, wetting agent, disintegrating agent, filler, etc., and pulverize it into wettable powder. Then add an appropriate amount of water for granulation, drying, and granulation to obtain 50% A·Cl Flutraniliprole water dispersible granules.

[0036] This embodiment is applied to the control of rice borer and sheath blight at the seedling stage of rice. 50% Jinggangmycin·Cyaniliprole water-dispersed granules were treated with rice seed dressing according to the active ingredient 5 g / 100 kg of seeds, and the seedlings were raised normally. 89.2-97...

Abstract

The invention discloses a pesticide composition which contains two active components, wherein a first active component is cyhalodiamide, and mass ratio of the first active component to the second active component is 10.0-50.0: 0.5-5.0. The pesticide composition is suitable for preventing and treating paddy rice, vegetable insect and disease.

Description

technical field [0001] The invention belongs to the field of pesticides, and in particular relates to a pesticide composition containing chlorofluranilide. Background technique [0002] In rice cultivation, rice seedling and seedling stages are very important. In the early spring season in my country, the temperature is very unstable. When the rice seedlings encounter low temperature weather and flooding, the rice seedlings often suffer from rotten seedlings. After investigation, the main reasons for the occurrence of rotten seedlings are bacterial wilt and bacterial wilt. At the same time, in the rice seedling and seedling stage, the overwintering generation of Diploss spp. adult eggs laying and hatching stage will also cause larval infestation and damage to rice. In the southern region, the combined occurrence of schizophrenia, blight, rice blast and sheath blight at the seedling stage of rice has become more and more serious, which has a great impact on agricultural pro...
