Examples
Embodiment 1
[0037] Example 1, Granules of 0.2% oxaziclozone:
[0038] Based on the total weight of granules, including: 0.2% oxazicone, 2% attapulgite, 0.15% polyvinylpyrrolidone, 0.1% reactive blue, and the balance of quartz sand.
[0039] According to the preparation method of the granule technical scheme 1 of the present invention, the above-mentioned materials are mixed evenly in a closed preparation kettle, granulated by coating method, dried at 120°C until the water content of the granules is 1%, and sieved, the particle size range is 4000 microns (μm), after passing the inspection, 0.2% oxaziclozone granules were obtained.
Embodiment 2
[0040] Example 2, 0.02% oxaziclozone granules:
[0041] Based on the total weight of granules, including: 0.02% oxaziclozone, 30% fertilizer, 0.5% slow-release agent, 5% binder, 0.3% coating agent, and the rest is kaolin filler.
[0042] According to the preparation method of the granule technical scheme two of the present invention, 0.02% oxaziclozone former medicine, 30% fertilizer, 0.5% slow-release agent, 5% binder, 0.3% coating agent, proper amount of filler are stirred in airtight After mixing evenly in the tank, add it to the granulation equipment for coating granulation, dry at 80°C-100°C until the water content of the granules is less than 3%, sieve (particle size range 2000um-4000um), after passing the inspection, Promptly obtain 0.02% oxaziclozone granules.
Embodiment 3
[0043] Example 3 In order to better verify the actual application effect of the present invention, the field efficacy test of granules of the present invention and bactericidal fertilizer granules is illustrated below with examples. The inventor carried out a test in Laokeng Village, Renshan Town, Huidong Province, Guangdong Province in July 2012.
[0044] Test agent and dosage:
[0045] (1) 0.02% oxaziclozone granules, dosage 3g.a.i / 667m 2 . (2) 0.2% oxaziclozone granules, dosage 3g.a.i / 667m 2 . Control drug: (3) 1% oxaziclozone suspension concentrate, dosage 3g.a.i / 667m 2 .
[0046] Targets for control: Annual weeds in rice throwing fields.
[0047] test results:
[0048] .
[0049] The test results show that the 0.02% oxaziclodione granules and 0.2% oxaziclomefone granules have excellent control effects on annual weeds in paddy field throwing seedlings, and the effect is better than 1% oxaziclomefone suspension concentrate, which is safe for rice.
