Problems solved by technology

Etoxazole inhibits the embryogenesis of mite eggs and the moulting process from larvae to adult mites. It is effective for eggs and larvae, but not for adult mites, but it has a good sterile effect on female adult mites.

Embodiment 1

[0026] Example 1: Determination of the combined effect of diafenthiuron and etoxazole mixed on red spider mite, Rosaceae ornamental flowers

[0027] 1.1 Purpose of the test

[0028] Red spider mite is the main pest of ornamental flowers in Rosaceae, and there are not many registered control agents. Both diafenthiuron and etoxazole are important agents for the control of red spider mites, and their targets are different. Reasonable mixing of the two may have certain complementarity. In order to determine the reasonable proportion and activity of the agents, this experiment measured the combined effect of diafenthiuron and etoxazole on red spider mite, and provided a reference for the development of diafenthiuron and etoxazole mixed suspension concentrate.

[0029] 1.2 Instruments and equipment

[0030] All are common laboratory instruments and equipment, including electronic balance (sensitivity 0.0001 g), pipette gun, pipette, beaker, cultured blood (9 cm), filter paper, s...

[0082] Electronic balance (accuracy 0.01g); laboratory sand mill; zirconium beads (diameter 1.0...

Embodiment 3

[0112] Example 3: Indoor determination test of 45% diafenthiuron · etoxazole suspension concentrate on the safety of Rosaceae ornamental flowers

[0113] 3.1 Purpose of the test

[0114] Rosaceae ornamental flowers have been planted more and more in the southern provinces of my country in recent years, and there is a great demand for pesticide use. According to the requirements of NY / T 1965.1-2010, the safety of 45% diafenthiuron-etoxazole mixed suspending concentrate (SC) sample spray treatment on three kinds of Rosaceae ornamental flowers described in Example 2 of the present invention was determined. The mass ratio of the active ingredients diafenthiuron to etoxazole in the preparation sample is 35:10. The recommended dosage is to dilute 5000-6000 times with water (the active ingredient is 75-90 mg / kg).

[0115] 3.2 Test crops

[0116] The ornamental flower variety of Rosaceae for testing is Cantonese rose ( Rosa kwangtungensis ), Red Hat Rose ( Rosa chinensis ) (th...

Abstract

The invention discloses a diafenthiuron and etoxazole mixed suspending agent capable of effectively controlling main pest mites of plants such as Rosaceae ornamental flowers. The formula of the mixed suspending agent consists of diafenthiuron raw drug, etoxazole raw drugs, a wetting dispersant, stabilizer, a thickening agent, an anti-freezing agent, a defoaming agent and water. The product has good physical and chemical stability. The accelerated storage test proves that various technical indexes of the product can meet the requirements, and the selected process is simple and feasible, does not have any special requirement on equipment and is suitable for industrial production. The test results of the combined effects of red spiders of Rosaceae ornamental flowers prove that the diafenthiuron and etoxazole are mixed, and the mixed suspending agent has an obvious synergistic effect on poisonous activity of red spiders of Rosaceae ornamental flowers such as Chinese roses and is high in toxicity on female adult mites of red spiders. The indoor test results of the safety of the Rosaceae ornamental flowers prove that the product is safe and hazard-free to tested Rosaceae ornamental flowers such as Rosa kwangtungensis, Rosa chinensis Jacq and roses, and the safety coefficient of the Rosaceae ornamental flowers is high.

Description

technical field [0001] The invention relates to a suspending agent mixed with diafenthiuron and etoxazole, and belongs to the technical field of pesticides. Background technique [0002] Research on pesticide formulations is an important aspect of pesticide development. A good formulation can maximize the function of active ingredients, cover the target to the greatest extent, reduce the amount of pesticides, facilitate the use of pesticides, and reduce the impact on the environment. On March 23, 2009, the Ministry of Industry and Information Technology issued the No. 29 Announcement on Issuing (Replacing) the Pesticide Production Approval Certificate, which clearly stated that since August 1, 2009, the approval certificate for pesticide emulsifiable concentrate products will no longer be issued . Therefore, the development of new pesticide suspension concentrates is an important part of the research on pesticide formulations. Pesticide suspension concentrate is a dispersi...
