Problems solved by technology

Once some virus-transmitting pests suck the juice of the virus plant, they will carry the virus for a long time, some will carry the virus for life, and some will pass the virus to the next generation, which often complicates the spread of the virus
[0006] At present, the first active ingredient is amino oligosaccharin, and the second active ingredient is spirotetramat or pyriproxyfen for use in vegetable pesticide compositions. preventive agents

Embodiment 1

[0017] Example 1: 10% oligosaccharin·spirotetramat microemulsion.

[0018]

[0019]

[0020] The above 10% oligosaccharin-spirotetramat microemulsion was used to control cucumber virus disease and whitefly. The test site was Huizhou City, Guangdong Province, and the test time was May 2014. The pesticide was applied at the initial stage of the virus disease, and spraying was used. medicine way. Using 150 times liquid of 5% oligosaccharin aqueous solution and 750 times liquid of 20% spirotetramat suspension concentrate as control agents, spray evenly with 150 times liquid of the above-mentioned agents. The control effect was investigated at 1d, 3d, 7d, and 20d after application, and the control effect at 3d after application was calculated in strict accordance with the calculation method stipulated in the National Standard of the People's Republic of China "Pesticide Efficacy Field Test Guidelines". The 3d corrected control effects of the above agents were 78.5%, 81.5%, a...

Embodiment 2

[0021] Example 2: 25% oligosaccharin · pyriproxyfen water dispersible granules.

[0022]

[0023] The above 25% amino oligosaccharin · pyriproxyfen water dispersible granule was used to control tomato virus disease and piercing and sucking mouthpart pests such as planthoppers and thrips. The test site was Guangyuan City, Sichuan Province, and the test time was July 2014. In the initial stage of viral disease, the pesticide is applied by spraying. With 150 times liquid of 5% oligosaccharin aqueous solution and 750 times liquid of 20% spirotetramat suspension concentrate as control agents, 150 times liquid of the above-mentioned 25% oligoaminosaccharin · pyriproxyfen water dispersible granule was evenly sprayed. The control effect was investigated at 1d, 3d, 7d, and 20d after application, and the control effect at 3d after application was calculated in strict accordance with the calculation method stipulated in the National Standard of the People's Republic of China "Pesticid...

Embodiment 3

[0024] Example 3: 15% oligosaccharin·spirotetramat suspension concentrate.

[0025]

[0026] The above 15% oligosaccharin·spirotetramat suspension concentrate products were used to prevent capsicum virus disease and piercing-sucking mouthpart pests such as planthoppers and thrips. The test site was Changde City, Hunan Province, and the test time was September 2014. In the early stage of viral disease, the pesticide is applied by spraying. With 150 times liquid of 5% oligosaccharin aqueous solution and 750 times liquid of 20% spirotetramat suspension concentrate as control agents, spray evenly with 150 times liquid of 15% oligoaminosaccharin·spirotetramat suspension concentrate. The control effect was investigated at 1d, 3d, 7d, and 20d after application, and the control effect at 3d after application was calculated in strict accordance with the calculation method stipulated in the National Standard of the People's Republic of China "Pesticide Efficacy Field Test Guidelines"...

Abstract

The invention relates to a pesticide composition for vegetables. A first active component of the pesticide composition is amino-oligosaccharin, and a second active component of the pesticide composition is spirotetramat or pyriproxyfen. Through indoor co-toxicity coefficient measurement, the pesticide composition has a synergistic effect on vegetable virus diseases and insect pests with piercing-sucking mouthparts such as plant hopper, thrips and the like. The pesticide composition can be made into common pesticide dosage forms such as a suspending agent, a microemulsion, water dispersible granules and the like, and is mainly used for controlling vegetable virus diseases and insect pests with piercing-sucking mouthparts such as plant hopper, thrips and the like.

Description

technical field [0001] The invention relates to a pesticide composition, the first active ingredient is amino oligosaccharin, and the second active ingredient is one of spirotetramat or pyriproxyfen, which is used for preventing and treating vegetable virus diseases and thorns such as planthoppers and thrips. Suction mouthparts pests. Background technique [0002] Amino oligosaccharins, also known as oligochitosaccharides for agriculture, are produced by unique biotechnology according to the growth needs of plants, and are divided into two types: solid and liquid. Oligochitosan itself is rich in C and N, which can be decomposed and utilized by microorganisms and used as nutrients for plant growth. Amino oligosaccharins (agricultural grade oligochitosaccharides) can inhibit the growth of some pathogens, affect the germination of fungal spores, induce changes in the morphology of mycelia, and changes in the biochemistry of the spores. It can stimulate genes in plants, produc...
