Problems solved by technology

[0005] Although pyridaben has no cross-resistance with existing insecticides and acaricides, long-term use of pest mites is bound to produce resistance to it; pyridaben also has a great risk of resistance

Embodiment 1

[0044] Take by weighing 400 grams of pyridaben, 4 grams of pyridaben, 30 grams of sodium alkyl polyoxyethylene ether sulfonate, 20 grams of polyoxyethylene polyoxypropylene ether block copolymer, 5 grams of carboxymethylcellulose, Add 2 grams of xanthan gum, 30 grams of sorbitol, 2 grams of potassium sorbate, 10 grams of silicone oil, and deionized water 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 After the thickness is less than 10 μm, a 40.4% cyanifen-pyridaben suspension concentrate is prepared.

Embodiment 2

[0046] Weigh 222 grams of pyridaben, 3 grams of pyridaben, 30 grams of sodium polyoxyethylene ether sulfonate, 10 grams of polyoxyethylene lauryl ether phosphate, 5 grams of carboxyethyl cellulose, 30 grams of Glycerol, 1 gram of formaldehyde, 10 grams of octanol, 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 After the thickness is less than 10 μm, 22.5% pyridaben-pyridaben suspension concentrate is prepared.

Embodiment 3

[0048] Weigh 294 grams of pyridaben, 6 grams of pyridaben, 50 grams of agricultural milk 600#, 30 grams of pan-60#, 30 grams of agricultural milk 1601, 50 grams of xylene, 40 grams of toluene, 50 grams of ethanol, 10 gram of triphenyl phosphite, completely dissolved and mixed uniformly, deionized water added to 1000 gram parts by weight, and stirred to obtain 30% pyridaben microemulsion.

Abstract

The invention discloses a mite killing composition containing cyenopyrafen and pyridaben and the application of the mite killing composition. The effective active components of the mite killing composition consist of a first active component, namely cyenopyrafen and a second active component, namely pyridaben, the weight ratio of the first active component to the second active component is 100:1-1:100, and the total content of the first active component and the second active component accounts for 3-85% of total weight of the composition. The composition can be compounded into preparation formulations of a suspending agent, a microemulsion, an aqueous emulsion, a dispersible oil suspending agent, wettable powder and an aqueous dispersible granule which are agriculturally allowable. The mite killing composition disclosed by the invention is reasonable in the components, has a good effect on European red mites, haw red spiders, tetranychus urticae, citrus red mites and tetrangychus cinnabarinus, and the mite killing effect of the mite killing composition is not simple superposition of the mite killing effects of the activity of all the components. Compared with a conventional single preparation, the mite killing composition not only has a remarkable mite killing effect but also has a remarkable synergistic effect, the dosage of the mite killing composition is reduced, and the mite killing composition has high safety to crops.

Description

technical field [0001] The invention relates to an acaricidal composition, which is composed of a first active ingredient, pyridaben, and an auxiliary agent, and belongs to the technical field of compound pesticides. Background technique [0002] Acarids are commonly called red spiders, which are arachnid pests. Mites are one of the important pests that harm many 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. Due to the large number of mites...
