Embodiment 1

[0028] Weigh 2.04 g98% pyriproxyfen former drug, dissolve with 10 g xylene, add 6 g fatty alcohol polyoxyethylene ether, 1 g castor oil ethylene oxide adduct, 0.2 g n-butanol to make oil phase, Mix evenly with 80.76g of water, shear at a high speed of 10000r / min for 5 minutes, and make 2% pyriproxyfen aqueous emulsion; weigh 6.32g of 95% hexaflumuron original drug, 4g of alkylphenol polyoxyethylene polyoxypropylene ether, After mixing 2 g calcium lignosulfonate, 0.15 g xanthan gum, 2 g ethylene glycol, and 85.53 g water, shear at a high speed of 10000 r / min for 5 minutes to be uniform, add a sand mill and grind to the required particle size (average particle size less than 3 microns) to make 6% hexaflumuron suspending agent; mix 2% pyriproxyfen aqueous emulsion and 6% hexaflumuron suspending agent according to 1:1 and then shear at 10000r / min for 5~10 minutes at high speed to form 4% pyriproxyfen · hexaflumuron suspoemulsion.

Embodiment 2

[0030] Take by weighing 10.21 g98% pyriproxyfen former drug, dissolve with 20 g xylene, add 6 g fatty alcohol polyoxyethylene ether, 1 g castor oil ethylene oxide adduct, 0.2 g n-butanol to make oil phase, Mix evenly with 62.59g of water, shear at a high speed of 10000r / min for 5 minutes, and make a 10% pyriproxyfen aqueous emulsion; weigh 31.58g of 95% hexaflumuron original drug, 5g of alkylphenol polyoxyethylene polyoxypropylene ether, After mixing 2.5g calcium lignosulfonate, 0.10g xanthan gum, 2g ethylene glycol and 58.82g water, shear at a high speed of 10000r / min for 5 minutes evenly, add sand mill and grind to the required particle size (average particle size less than 3 microns) to make 30% hexaflumuron suspension; mix 10% pyriproxyfen aqueous emulsion and 30% hexaflumuron suspension according to 1:1, and then shear at 10000r / min for 5-10 minutes at high speed to form 20% pyriproxyfen · hexaflumuron suspoemulsion.

Embodiment 3

[0032] Weigh 5.10 g of 98% pyriproxyfen technical, 5.26 g of 95% hexaflumuron technical, and 88.14 g of kaolin, mix well, then add 15 g of 1% polyvinyl alcohol aqueous solution and mix to make a soft material. A good soft material is granulated by an extrusion granulator and dried to form 10% pyriproxyfen·hexaflumuron granules.

Abstract

The invention discloses a pesticide composition containing pyriproxyfen and hexaflumuron, and belongs to the technical field of pesticides. Pyriproxyfen and hexaflumuron in the pesticide composition belong to insect growth regulators; and functional mechanisms of pyriproxyfen and hexaflumuron are different, and pyriproxyfen belongs to juvenile hormone analogues, which disturbs the insect hormone balance, while hexaflumuron belongs to chitin synthesis inhibitor class, which has functions of inhibiting the chitin synthetase activity and hindering a larval molting effect. According to the pesticide composition, pyriproxyfen and hexaflumuron are mixed to play an obvious synergistic interaction function on leek late eye fungus gnat 4-instar larva, thereby improving the prevention and control effect, greatly reducing the dosage in the field, effectively reducing environmental pollution and pesticide residues and reducing the cost. In addition, two single dosages have different mechanical functions, so that the overcoming of injurious insect resistance and the delaying of the injurious insect resistance are facilitated due to the mixed using of the two single dosages. The pesticide composition containing pyriproxyfen and hexaflumuron is low in toxicity, quick in response and wide in disease prevention and treatment, and has a good pesticide effect.

Description

technical field [0001] The invention relates to the technical field of pesticides, in particular to a pesticide composition containing pyriproxyfen and hexaflumuron. Background technique [0002] Pyriproxyfen, 4-phenoxyphenyl-(RS)-[2-(2-pyridyloxy)propyl]ether, is a highly active juvenile hormone analog insect growth regulator, It can disturb the hormone balance in insects, thereby affecting embryonic development, insect metamorphosis and eclosion. Its main function is in the pupation and eclosion stage of insects, interrupting molting, and can inhibit adult eggs from laying eggs, effectively reducing the survival rate of eggs, and is harmful to Diptera pests. The effect is good, and it is mainly used to control sanitary pests. Physical and chemical properties of pyriproxyfen: pure product is crystalline, melting point: 45-47 ℃, relative density 1.23 (20 ℃), vapor pressure 0.29×10-3Pa (20 ℃), storage conditions: 0-6 ℃. (20~25 ℃) solubility: xylene 500 g / L, hexane 400 g / L, ...
