Embodiment 1

[0042] Weigh 200 grams of fluazinam, 100 grams of fluazin, 40 grams of sodium hydroxypropyl cellulose, 50 grams of acrylic acid homopolyoxysodium salt, 30 grams of sodium sulfate, 20 grams of gum arabic, 25 grams of butanol, attapulgite Add to 1000 grams by weight. The above slurry is wet pulverized by a sand mill to form a suspension slurry, and then spray-dried and granulated, and the granulated particles are sieved to obtain a 30% fluazinam·flufenazine dry suspension concentrate.

Embodiment 2

[0044] Weigh 140 grams of fluazinam, 60 grams of fluazin, 80 grams of sodium dodecylbenzene sulfonate, 30 grams of sodium alkylnaphthalene sulfonate, 40 grams of polyvinylpyrrolidone, 40 grams of polyvinylpyrrolidone, 30 grams of hexanol, White carbon black is added to 1000 gram parts by weight. The above slurry is wet pulverized by a sand mill to form a suspension slurry, and then spray-dried and granulated, and the granulated particles are sieved to obtain a 20% fluazinam·flufenazine dry suspension concentrate.

Embodiment 3

[0046] Weigh 300 grams of fluazinam, 50 grams of fluazin, 50 grams of polyoxyethylene polyoxypropylene ether block copolymer, 50 grams of lauryl polyoxyethylene ether phosphate, 30 grams of bentonite, 20 grams of polyethylene Alcohol, 25 grams of sorbitol, 8 grams of sodium benzoate, 15 grams of hexanol, and deionized water are added to 1000 grams by weight. The above raw materials are mixed, dispersed at high speed for 30 minutes, and sanded with a sand mill to a particle size of D 90 A 35% fluazinam·flufenazine suspension was prepared after the thickness was less than 10 μm.

Abstract

The invention discloses an acaricide composition containing fluazinam and flutenzine. The effective active components of the acaricide composition comprise a first active component and a second activecomponent, wherein the first active component is the fluazinam, and the second active component is the flutenzine, the weight ratio of the first active component to the second active component is equal to (1 to 10)-(20 to 1), and the sum of the contents of the first active component and the second active component is 1-70% of the total weight of the composition. The acaricide composition can be prepared into a dry suspending agent, a suspending agent, a dispersible oil suspending agent, water dispersible granules and wettable powder which are agriculturally acceptable. The composition provided by the invention is reasonable in components, and has good effects on citrus red spider, iron wall lice, tetranychus urticae and tetranychus cinnabarinus; the acaricidal effect of the acaricide composition is not a simple superposition of the activities of all the components; compared with the existing single preparation, the composition has a significant synergistic effect besides an obvious acaricidal effect, and is less in consumption and good in crop safety.

Description

technical field [0001] The invention relates to an acaricidal composition, which is composed of a first active ingredient fluazinam, a second active ingredient flufenazine and an auxiliary agent, and belongs to the technical field of compound pesticides. Background technique [0002] Harmful mites belong to the order Arachnida Acarina, and there are many kinds of them, which harm a variety of crops. Often gather on the back of the leaves, adults and nymphs use their mouthparts to pierce the leaves and suck the juice, which damages the chlorophyll of the plant and affects photosynthesis. Affected leaves often have off-white dots or white plaques, and some cause cell proliferation in the damaged part, making the leaves protrude in the shape of galls or galls, or the leaves are curled and shrunk. Leaf fall causes plant death. In addition, many pest mites transmit plant viral and fungal diseases. Agricultural pest mites are one of the obstacles to agricultural production. D...
