Embodiment 1

[0014] Bioassay Example 1: Indoor toxicity determination of Nitenpyram and pyridaben to Panonychus citrus.

[0015] Test object: Panonychus citrus, reared indoors, with good growth and moderate resistance.

[0016] Test method: cut citrus leaves into small pieces of 3cm×3cm, put them into a petri dish with a diameter of 9cm, and line the dish with filter paper. After the citrus leaves were sprayed once, the leaves were turned over and 20 larvae were connected, and then sprayed again, each spraying volume was 10ml, and clear water was used as a control. The death situation was checked 1d, 3d, 5d, 10d, 20d after treatment. Each treatment was repeated 3 times, and then treated in the spray tower.

[0017] The test agent used 95% of the original drug of nitenpyram and 97.7% of the original drug of pyridaben, and the required preparations were prepared by the R&D Center of Guangdong Zhongxun Agricultural Science Co., Ltd.

[0018] Adjusted mortality rates for each treatment wer...

Embodiment 1

[0023] Formulation Example 1: 25% Nitenpyram · Pyridaben water dispersible granules.

[0024] Nitenpyram 7.5%, Pyridaben 17.5%, Mineral Oil 5%, Nonylphenol Polyoxyethylene Ether 8%, Fast T 4%, Sodium Lauryl Sulfate 2%, Sodium Lignosulfonate 10%, Naphthalenesulfonate 4%, bentonite to make up to 100%.

[0025] The above formula is dry-milled, granulated, dried, and sieved according to the proportion to prepare 25% nitenpyram·pyridaben water-dispersible granules.

[0026] This embodiment is used to control rice planthopper. The test site was Changde City, Hunan Province, and the test time was September 2010. The pesticide was applied during the peak period of rice planthopper damage, and the method of spraying was adopted. Dilute 25% Nitenpyram · Pyridaben water dispersible granules mixed with water 1500 times and spray evenly, the control effect is 93.0% and 95.2% 3 days and 7 days after application. Dilute 10% nitenpyram solution with water 1500 times and 20% pyridaben wet...

Abstract

The invention discloses a nitenpyram and pyridaben containing pesticide composite, in which the pbm (parts-by-mass) ratio of nitenpyram to pyridaben is (1:20)-(20:1). A compound of the two effective components has an obvious synergistic effect, so that the control efficiency is improved, the control spectrum is expanded, and the dosages of the pesticides are reduced, thereby reducing the cost and the pollution to the environment. The pesticide composite disclosed by the invention is suitable to be used for preventing and controlling various pests such as aphids, plant hoppers, thrips, whiteflies and red spiders of crops such as vegetables, paddy rice and fruit trees.

Description

technical field [0001] The invention relates to a pesticide composition, which uses nitenpyram and pyridaben as active ingredients, and belongs to the field of pesticide compounding. Background technique [0002] The loss of crop yield due to pests and diseases of crops is immeasurable, and chemical control is the main way to control the occurrence of pests and diseases. Therefore, it is necessary to use a large amount of pesticides for pest control every year to recover the loss of crop yield. In recent years, the harm of insect pests on crops such as rice, fruit trees, vegetables, flowers and various economic crops has become more and more serious, and due to the abuse of pesticides, the resistance of pests to pesticides has become more and more serious, resulting in pest control effects. decrease year by year. Therefore, there is a need for pesticide varieties with better pest control effects. [0003] Nitenpyram belongs to the nicotinimide class. It is another new prod...
