Embodiment 1

[0025] Example 1 10% chlorfenapyr-propargite emulsion in water

[0026] Chlorfenapyr 5 g, propargite 5 g, toluene 10 g, No. 33 10 g, ethylene glycol 8 g, xanthan gum 0.6 g, organosiloxane 0.2 g, and water added to 100 g.

[0027] Its preparation process is as follows: melt chlorfenapyr and propargyl acarid solvent (toluene) to form a uniform oil phase; mix emulsifier (No. 33), antifreeze agent (ethylene glycol), thickener (xanthan gum ), antifoaming agent (organosiloxane) and water are stirred and mixed to form a uniform water phase; the oil phase is poured into the water phase, and stirred at 20 ° C for 5 minutes at a speed of 1000 rpm to prepare the described 10% chlorfenapyr-propargite emulsion in water.

Embodiment 2

[0028] Example 2 10% chlorfenapyr-propargite emulsion in water

[0029] Chlorfenapyr 6.7 g, propargid 3.3 g, xylene 20 g, No. 34 18 g, propylene glycol 8 g, gum arabic 0.6 g, gelatin 0.2 g, polyether 0.4 g, water to 100 g.

[0030] Its preparation process is as follows: melt chlorfenapyr and propargyl acarid solvent (xylene) to form a uniform oil phase; mix emulsifier (No. 34), antifreeze agent (propylene glycol), thickener (gum arabic and gelatin) ), antifoaming agent (polyether) and water were stirred and mixed to form a uniform water phase; stirred at 21°C for 8 minutes at a speed of 1200 rpm, and poured the water phase into the oil phase to form the 10 % Chlorfenapyr · propargite emulsion in water.

Embodiment 3

[0031] Example 3 10% chlorfenapyr-propargite emulsion in water

[0032]Chlorfenapyr 7.5 g, propargite 2.5 g, toluene 20 g, propylene glycol 10 g, Tween 20 18 g, urea 6 g, sodium alginate 2 g, natural rubber 6 g, organic silicone 0.4 g, water added to 100g.

[0033] Its preparation process is as follows: melt chlorfenapyr and propargyl acarid special solvent (toluene) to form a uniform oil phase; mix emulsifier (Tween 20), antifreeze agent (urea), thickener (sodium alginate and Natural rubber), antifoaming agent (organic silicone) and water are stirred and mixed to form a uniform water phase; the oil phase is poured into the water phase, and stirred at 22 ° C for 10 minutes at a speed of 1500 rpm to obtain the prepared The 10% chlorfenapyr-propargite aqueous emulsion mentioned above.

Abstract

The invention provides an acaricide water emulsion composition and a preparation method of the acaricide water emulsion composition and belongs to the technical field of compound pesticide. The acaricide water emulsion composition comprises the following effective ingredients in percentage by weight: 5 to 8 percent of chlorfenapyr and 2 to 5 percent of propargite, wherein the weight ratio of the chlorfenapyr to the propargite is 1:1-4:1. The preparation method of the water emulsion composition comprises the following steps that: the chlorfenapyr and the propargite are dissolved by solvents for forming a uniform oil phase; emulsifying agents, anti-freezing agents, thickening agents and water are stirred and mixed for forming a uniform water phase; and the water phase is poured into the oil phase, or the oil phase is poured into the water phase, the stirring is carried out for 5 to 20 minutes at 22 DEG C +/-2 DEG C at the rotating speed being 1000 to 2000 revolution/minute, and the acaricide water emulsion composition is obtained. The acaricide water emulsion composition and the preparation method have the advantages that the obvious acaricide synergy effect is realized, the dosage is reduced, the toxicity effect on non-target organisms is reduced, and the environment-friendly effect is realized.

Description

technical field [0001] The invention belongs to the technical field of compound pesticides, and relates to an acaricidal aqueous emulsion composition containing chlorfenapyr and propargid. At the same time, it also relates to a preparation method of the acaricidal aqueous emulsion composition. Background technique [0002] Chlorfenapyr, English name Chlorfenapyr, Chinese common name Chlorfenapyr. The chemical name is 4-bromo-2-(4-chlorophenyl)-1-ethoxymethyl-5-trifluoromethylpyrrole-3-carbonitrile, which is a new type of pyrrole with low toxicity and high efficiency for insecticide, Acaricide, which has stomach toxicity and certain contact and systemic effects on pests, and has excellent control effects on borer, piercing and chewing mouthpart pests and mites. Chlorfenapyr is a kind of insecticide precursor, which itself has no poisonous killing effect on insects, and is transformed into a drug of specific insecticidal active compounds under the action of multifunctional o...
