Embodiment 1

[0030] Example 1 Synergistic test of emamectin B2 benzoate and fluopyram on isolated pine wood nematodes.

[0031] The pine xylophilus nematodes used in the experiment were collected from the pine forest (Pine massoniana) of Shangfu Village Committee, Yulao Town, Fengkai County, Zhaoqing City, Guangdong Province. The diseased and dead tree wood was cut into thin slices, and the nematodes were separated by the Berman funnel method. After the obtained nematodes were confirmed as pine wood nematodes by microscopic examination (the identification method refers to the pine wood nematode quarantine technical operation method issued by the Jiangsu Provincial Forestry Bureau), 10 female adults and 4 male adults were picked and placed in a place covered with Botrytis cinerea. Bacteria Botrytis cinerea was cultured on potato dextrose agar (PDA) plates at 25°C in an incubator. After the nematodes have basically eaten the mycelium, further expand the culture. Finally, the nematodes cultu...

Embodiment 1

[0045] Formulation Example 1 Formulation A

[0046]1% emamectin B2 benzoate 10% dispersible oil suspension concentrate, by weight, its raw material formula is: get emamectin B2 benzoate 1%, fluopyram 10% gram, castor oil polyoxyethylene ether 15%, sec-butyl acetate 15%, sodium lignosulfonate 2%, glycerol 5%, turpentine oil supplemented to 100%; active ingredient and other additives are mixed, after 8000 revolutions per minute high-speed shearing machine shears and disperses for 30 minutes, and after sanding in a sand mill for 30 minutes, a highly dispersed and stable suspension system is formed in an oily medium to prepare 1% emamectin B2 benzyl Salt 10% dispersible oil suspension concentrate.

Embodiment 2

[0047] Formulation Example 2 Formulation B

[0048] 1% emamectin B2 benzoate 10% dispersible oil suspension concentrate, by weight, its raw material formula is: get emamectin B2 benzoate 1%, fluopyram 10% g, 15% castor oil polyoxyethylene ether, 15% sec-butyl acetate, 2% sodium lignosulfonate, 5% glycerin, and palm oil to make up to 100%; mix active ingredients and other additives, After shearing and dispersing with a high-speed shearing machine at 8000 rpm for 30 minutes and sanding in a sand mill for 30 minutes, a highly dispersed and stable suspension system is formed in an oily medium to prepare 1% emamectin B2 benzene Formate 10% dispersible oil suspension concentrate.

Abstract

The invention discloses a pesticide composition for preventing and treating bursaphelenchus xylophilus. The pesticide composition contains fluopyram and emamectin benzoate B2 serving as active ingredients.

Description

technical field [0001] The invention belongs to the technical field of pesticides, and specifically discloses a pesticide composition for preventing and treating pine wood nematode, which contains active ingredients A and B, wherein A is selected from emamectin B2 benzoate, and B is selected from From fluopyram. [0002] technical background [0003] The spread of pine wood nematode (Bursaphelenchus xylophilus) disease in China has caused a large number of pine trees to wither and die, and pine forests in some areas have been destroyed, causing ecological disasters; in some scenic spots, due to the damage of pine wood nematode disease, a large number of valuable ancient pines have disappeared, causing irreparable losses. Controlling the vector insect, Monochamus alternatus, is still the current technical method for controlling pine wood nematode disease. Most of these methods lack pertinence or are inconvenient to use for tall trees in mountainous areas, are difficult to put...
