Problems solved by technology

[0005] At present, there are few effective pesticides for controlling rice planthoppers in rice production. The cost of pymetrozine for controlling rice planthoppers is relatively high, and there has been a situation of gradual and continuous use. Gradually increase, the cost of prevention and control increases again

Embodiment 1～ Embodiment 5

[0012] The two single agents were mixed according to the ratio of flusalthrin and pymetrozine (active ingredients) 1:1, 1:2, 1:4, 1:8, 1:16 respectively to form a binary compound preparation. Example 1 to Example 5, carry out indoor bioassay synergism. The test agents were flusalthrin (produced by Jiangsu Yangnong Chemical Group Co., Ltd.) and pymetrozine (produced by Jiangsu Anbang Electrochemical Co., Ltd.); the test insects were 2-3 instar nymphs of brown planthopper. Take by weighing a certain amount of flusalthrin and the former medicine of pymetrozine, be made into 1000ppm mother liquor with acetone and emulsifier Triton X100 (0.1%), two kinds of single agents are respectively according to above-mentioned embodiment 1~embodiment 5 The ratio is made into a binary compound agent, 1000ppm flusalthrin mother liquor, and 1000ppm pymetrozine mother liquor respectively diluted with water to 5 concentrations, and treated with clear water as a blank control; using the seedling so...

Embodiment 6

[0017] Prepare 15% flusalthrin · pymetrozine wettable powder, the weight ratio of each component is:

[0018] Fluthrin (active ingredient) 5%

[0019] Pymetrozine (active ingredient) 10%

[0020] Sodium dodecylbenzenesulfonate 1%

[0021] NNO 3%

[0022] Silica 10%

[0023] Sodium lignosulfonate 4%

[0024] Kaolin balance

[0025] First, 5% of the total weight of flusalthrin and 10% of Nongru 2201 are adsorbed with 10% white carbon black, and then with 10% of the total weight of pymetrozine, 1% sodium dodecylbenzenesulfonate, Mix 4% sodium lignosulfonate and the remainder of kaolin, jet mill, and mix and stir in a conical mixer for 30 minutes to prepare 15% flusalthrin·pymetrozine wettable powder.

Embodiment 7

[0027] Prepare 16% flusalthrin · pymetrozine wettable powder, the weight ratio of each component is:

[0028] Fluthrin (active ingredient) 8% (weight, the same below)

[0029] Pymetrozine (active ingredient) 8%

[0030] Sodium dodecylbenzenesulfonate 1%

[0031] NNO 3%

[0032] Silica 12%

[0033] Sodium Lignosulfonate 4%

[0034] Kaolin balance

[0035] First, 8% of the total weight of flusalthrin and 10% of Nongru 2201 are adsorbed with 12% white carbon black, and then with 8% of the total weight of pymetrozine, 1% sodium dodecylbenzenesulfonate, Mix 4% sodium lignosulfonate and the remainder of kaolin, jet mill, and mix and stir in a cone mixer for 30 minutes to prepare 16% flusalthrin·pymetrozine wettable powder.

[0036] Carry out field drug efficacy test (see table 2) to the effect of embodiment 6 preventing and controlling the adults of SBPH, test drug species: 5% flusalthrin emulsifiable concentrate, 25% pymetrozine wettable powder, 15% flusalthrin · Pymetrozine...

Abstract

The invention belongs to the technical field of chemical control for pests, and relates to a compound pesticide with silafluofen for controlling rice planthoppers. The active ingredients of the compound pesticide with the silafluofen comprise the silafluofen and pymetrozine, wherein, the weight ratio of the two components in the compound pesticide is 1:1 to 1:16. Compared with a common rice planthopper pesticide, the compound pesticide has the following advantages: (1) compared with a single preparation, the compound pesticide has an obvious synergistic effect on rice planthoppers and can obviously improve control effect; (2) the compound pesticide can replace high-toxicity pesticides (for example, methamidophos, and the like), reduces the amount of the pesticide to be used, and lowers environmental pollution and residue in agricultural products; (3) the compound pesticide can prolong the drug resistance of the rice planthoppers to the single pesticide; and (4) the compound pesticide is quick in desinsection speed and long in effect lasting period, and can reduce cost compared with the single pesticide.

Description

technical field [0001] The invention belongs to the technical field of pest chemical control, and relates to a compound insecticide containing silafluofen for controlling rice planthopper. Background technique [0002] Rice planthopper (including brown planthopper, brown planthopper, and white-backed planthopper) is a kind of rice pest with strong migratory ability (except for brown planthopper) and extremely fast reproduction speed. Normally, the 1000-grain weight is reduced, and in severe cases, the whole plant will wither, resulting in a substantial reduction in rice production, and it can also spread viruses and cause stripe leaf blight, which is a key pest for rice control. For a long time, the control of rice planthoppers has mainly relied on imidacloprid, organophosphorus and their compounding agents. Among them, the use of highly toxic organophosphorus pesticides has been banned. Due to the long-term single and continuous use of imidacloprid, brown planthoppers and b...
