Embodiment 1

[0015] Example 1: Indoor bioassay test of iprodione, sulfoxaflor and their mixture against tomato root-knot nematode.

[0016] Test method: Take the severely damaged tomato root system, rinse it gently with tap water, gently pick out the milky white oocysts on the diseased root with a dissecting needle, put it into a small petri dish with a diameter of 6 cm, add a small amount of sterile water, and incubate at 25°C. Incubate in an incubator for 3 to 4 days, collect the 2nd instar larvae, and add sterile water to make a suspension with a certain concentration (about 500 / ml) for later use.

[0017] Five concentration gradient treatments were set, and sterile water was used as the blank control. Take a 96-well cell culture plate, add 150 microliters of prepared medicines of different concentrations to each well, and then add an equal volume of root-knot nematode suspension, culture at 25°C, and check for root-knot nematodes at different times after treatment The number of surviv...

Embodiment 2

[0022] Example 2: 2% iprodione·sulfoxaflor granules.

[0023]

[0024] Mix the above materials evenly in a closed blending kettle, granulate by coating method, dry at 120°C until the water content of the granules is 1%, sieve, and the particle size range is 2000 microns (μm). After passing the inspection, you can get 2 % Iprodione · Sulfoxaflor Granules.

Embodiment 3

[0025] Example 3: 20% iprodione·sulfoxaflor suspension concentrate.

[0026]

[0027]

[0028] The above-mentioned materials are pre-crushed in proportion, then added to a sand mill for grinding, and prepared after high-shear mixing to prepare a 20% iprodione·sulfoxaflor suspension concentrate.

Abstract

The invention relates to a pesticide composition for preventing and controlling meloidogyne. Iprodione and sulfoxaflor are used as active ingredients. The composition of the iprodione and the sulfoxaflor has a synergetic effect on the meloidogyne, improves the prevention and control effect, and delays resistance of the meloidogyne to the iprodione and the sulfoxaflor.

Description

technical field [0001] The invention belongs to the technical field of pesticide compositions, and relates to the combination of effective components iprodione and sulfoxaflor for preventing and treating root-knot nematodes and improving the actual control effect. Background technique [0002] Root-knot nematode (Meloidogyne) is a highly specialized omnivorous plant pathogenic root-knot nematode. Root-knot nematodes mainly damage the roots of various vegetables, showing more lateral roots and fibrous roots than normal, and forming spherical or conical white nodules of various sizes on the fibrous roots of young roots, some of which are bead-shaped. The aboveground part of the damaged plant grows short and slow, with abnormal leaf color, few fruits, low yield, and even premature death of the plant. Root-knot nematodes can also cause fungal and bacterial diseases, such as fusarium wilt, damping-off, root rot, soft rot and other root diseases. [0003] Iprodione is a dicarbox...
