Problems solved by technology

For example, the prepared wettable powder is easy to cause product sticking, is not easy to disperse and suspend in water, or clogs the nozzle, and causes precipitation in the sprayer, etc., resulting in uneven spraying and local phytotoxicity of crops. The main reason is that it helps There are different defects in the selection of agents and fillers
[0006] 3), the problem of compounding, through the toxicity test, heat storage stability test and co-toxicity coefficient measurement of several specific proportions disclosed by the above-mentioned several bactericidal compositions, it was found that no obvious additive synergistic effect could be achieved

Abstract

The invention discloses a famoxadone and mancozeb compound water dispersible granule and a preparation method thereof, and relates to the technical field of the treatment of tomato early blight. The granule at least is prepared from 6.25 parts of famoxadone, 62.5 parts of mancozeb, 8 parts of calcium lignosulphonate, 4 parts of polycarboxylate, 3 parts of alkyl naphthalene sulfonate, 5 parts of ammonium sulfate, 2 parts of polyethylene glycol, and kaoline which complements 100 parts. The method comprises the following steps: mixing raw materials other than polyethylene glycol, crushing the raw materials into powder through an ultramicro airflow crusher, feeding the raw materials into a fluidized bed dry granulator, performing granulation in a fluidized bed at 50 to 70 DEG C through the polyethylene glycol, performing drying in a dryer, obtaining a product after screening, then performing sampling analysis, and performing metering, packaging and storage after the product is qualified. The granule has the advantages that a compounded famoxadone and mancozeb compound water dispersible granule which is 68.75 percent is mixed at a ratio of 1:10, an obvious synergism range can be realized, and preparations with other ratios cannot achieve the obvious synergism range.

Description

technical field [0001] The invention relates to the technical field of tomato early blight prevention and control, in particular to a compounded water-dispersible granule of oxafluconone and mancozeb and a preparation method thereof. Background technique [0002] At present, the existing bactericidal composition for the prevention and treatment of tomato early blight, for example, the Chinese patent "CN 105379772A" discloses a "organic titanium sodium mixture for the prevention and treatment of tomato early blight", in which the effective active ingredients are chitosan spherical nano-titanium and 0.6% of Ti, 30% of garlic, 5% of sodium carbonate, 2.5% of foliar film-forming agent, the balance is 100% of water, 1.5% of fermentation bacteria by volume; Composition of Rhodopseudomonas palustris to control tomato early blight caused by Alternaria solani. In addition, the Chinese patent "CN 104230549 A" ​​discloses a "tomato multifunctional medicinal fertilizer and its preparat...
