Problems solved by technology

[0002] Cruciferous vegetables are vegetables with the most varieties and the largest cultivation area, and the types of pests and diseases are also the most, and the damage is also the most severe. It is one of the main restrictive factors for the production of cruciferous vegetables; In the seedling stage, due to the rampant soil pests such as grubs, dayworms, mole crickets, cutworms, etc., the roots are often severely damaged, causing the whole plant to wither, lacking seedlings and breaking ridges; and rampant aphids, mites, and flea beetles on the leaves of seedlings, especially when encountering Drought can also cause vegetable plants to wither and die, posing a threat to the survival of vegetable seedlings; on the other hand, cruciferous vegetables are seriously damaged by soil-borne diseases such as blight, root rot, damping-off, etc. characteristics, making it extremely difficult to control diseases of cruciferous vegetables
[0003] Pesticide preparations containing a single active ingredient are generally difficult to control pests and diseases at the same time in the pest control of cruciferous vegetables, and there are certain defects. The pollution of cruciferous vegetables and the environment can overcome the above shortcomings through a reasonable mixture of single active ingredients

Embodiment 1

[0036] Example 1: 40% fluopyram · cyantraniliprole granules (1:1)

[0037]

[0038] The preparation method of the granules is as follows: uniformly mix the above-mentioned raw materials in a mixing tank, extrude, granulate, dry and finally sieve to obtain 40% fluopyram·cyantraniliprole granules.

Embodiment 2

[0039] Example 2: 25% fluopyram · cyantraniliprole suspension seed coating (2:3)

[0040]

[0041] The preparation method of the suspension seed coating agent is as follows: firstly mix each auxiliary agent, mix uniformly through high-speed shearing, add active ingredients fluopyram and cyantraniliprole, and grind in a ball mill for 2-3 hours until the suspending agent 25% fluopyram · cyantraniliprole suspension seed coating can be prepared if the particle size is below 5 microns.

Embodiment 3

[0042] Example 3: 26% fluopyram · cyantraniliprole granules (6:7)

[0043]

[0044] The preparation method of the granule: mix the above-mentioned materials in proportion, and in a mixer, evenly coat the finely ground active ingredient on the carrier wetted by polyethylene glycol, and then 26% fluopyric acid can be obtained Amide · cyantraniliprole granules.

Abstract

The invention relates to a compound composition for preventing and controlling pests on brassicaceous vegetables and belongs to the technical field of pesticides. The active component of the compoundcomposition comprises fluopyram and cyantraniliprole, and the weight ratio of the fluopyram to the cyantraniliprole is (1:30)-(50:1). Through compounding of the fluopyram and the cyantraniliprole in areasonable range, the compound composition has a great prevention and controlling effect on multiple kinds of harmful organisms, the effect of controlling the diseases and pests is achieved, and particularly the compound composition has a great effect of preventing and controlling phyllotreta striolata fabricius, meloidogyne artiellia and blackened stem base.
