Problems solved by technology

Since the epidemic of viral diseases is mainly caused by insects carrying viruses such as aphids, leafhoppers, planthoppers, whiteflies and other vector insects, the single use of medicaments for the prevention and treatment of viral diseases is not very effective. , cannot fundamentally control the damage caused by virus diseases on crops

Embodiment 5

[0026] Formulation Example 5: 50% sterenol·tolfenpyrad water dispersible granules.

[0027] Steenol 35%, Tolfenpyrad 15%, sodium lauryl sulfate 5%, alkylphenol polyoxyethylene ether 10%, ammonium sulfate 2%, and kaolin make up 100%. Mix the above-mentioned active ingredients, wetting agent, dispersant, disintegrant and filler evenly, pulverize with an ultrafine jet mill, knead, and then add to a fluidized bed granulation dryer for granulation, drying, and sieving. 50% sterenol·tolfenpyrad water dispersible granules can be prepared.

[0028] Formulation Example 6: 80% sterenol·tolfenpyrad wettable powder.

[0029] Sterenol 50%, Tolfenpyrad 30%, Sodium dodecylbenzene sulfonate 10%, Polyoxyethylene glycerol fatty acid ester 5%, Kaolin makes up 100%. The above-mentioned effective ingredients, wetting agent, dispersant and filler are mixed, mechanically pulverized and then pulverized by airflow, and mixed uniformly, to obtain 80% sterenol·tolfenpyrad wettable powder.

Embodiment 1

[0030] Bioassay Example 1: Indoor combined virulence test of sterenol and tolfenpyrad on rice stripe leaf blight.

[0031] Cultivate potted susceptible rice varieties indoors. When the seedlings grow to 1 leaf and 1 heart to 2 leaves and 1 heart, the inoculation identification is carried out. Each pot cover is covered with a transparent cover, and the top is sealed with gauze. The amount of insects required is calculated according to 5 Laodelphax striatellus per seedling, and 2 to 3 instar Laodelphax striatellus (with a poisonous rate of about 40%) is connected. Deworming twice a day, so that the tested rice seedlings are evenly infected by the poison. Spray the formulated agents with different concentrations evenly on the test seedlings, each treatment 50 plants, 4 repetitions, 14 days after the administration, the disease condition is graded and the control effect is calculated, and the EC is used 50 Value to calculate the co-toxicity coefficient.

[0032] Table 1. Indoor combin...

Embodiment 2

[0036] Bioassay Example 2: Field efficacy test of compound sterenol and tolfenpyrad to control rice stripe disease.

[0037] Apply the pesticide for the first time 20-30 days after the rice is transplanted, and apply the pesticide again at an interval of 7 days for a total of 3 sprays. The survey results were conducted at 7d and 14d after the three administrations, and the disease index was counted to calculate the control effect.

[0038] It can be seen from Table 2 that after three application of 7d and 14d, 25% tolfenpyrad·sterenol suspension used 250-300g.ai / ha to control rice stripe blight better than 15% tolfenpyrad Emulsifiable concentrate and 1% sterenol aqua are used alone, and the control effect is above 85%. At the same time, the compound agent was not found to cause phytotoxicity to rice during the experimental investigation.

Abstract

The invention discloses a pesticide composition containing sterene alcohol and tolfenpyrad. The pesticide composition comprises sterene alcohol serving as a first effective component, tolfenpyrad serving as a second effective component and a commonly-used auxiliary component, wherein the weight ratio of sterene alcohol to tolfenpyrad is 20:1 to 1:20. A lot of experiments prove that the pesticide composition has an obvious synergistic interaction function; by preventing and controlling vector insects which can spread the virus disease and utilizing the treatment function of the virus disease, the prevention and control effect of the virus disease on crops can be obviously improved.

Description

Technical field [0001] The invention relates to pesticide preparations and their application fields, in particular to a pesticide composition with sterenol and tolfenpyrad as effective ingredients, which is applied to the prevention and control of viral diseases on crops and vector insects that spread viral diseases. Background technique [0002] Viral diseases pose a serious threat to the yield and quality of crops worldwide. According to statistics, the annual output reduction is 10-30% and the economic loss is about 20 billion US dollars. my country is a large agricultural country, and the economic losses caused by virus diseases to grain production, horticultural crops, and cash crops are about tens of billions every year. As the epidemic of viral diseases is mainly caused by virus-carrying insects such as aphids, leafhoppers, planthoppers, whiteflies and other vector insects, therefore, the use of a single agent for the prevention and control of viral diseases is not ideal. ...
