Embodiment Construction

[0031] See figure 1 As shown, according to the preparation method of the medicine fertilizer granule of the present invention, 0.1%~10% of the original medicine of spiroxamine ethanolamine salt, 0.5%~3% of dispersing aid, 0.1%~2% of sustained release agent, 0.1%~5% Attractant, 30%-60% carrier fertilizer and filler are mixed evenly in a closed mixing tank, granulated by coating method, dried at 110°C-120°C until the water content of the granules is less than 3%, sieved (particle size range 2000um ~4000um), after passing the inspection, the required medicinal fertilizer granules will be obtained. The powder sieve is crushed and returned to the mixing tank for reblending. Unqualified products are returned to the mixing tank for re-mixing after inspection and analysis of the reasons. The mixing adopts a step-by-step method. Raw materials with low component content are first mixed with a certain quality of dispersing aids or fillers and then mixed with other materials to ensure t...

Abstract

The invention relates to a medicine fertilizer granular formulation used for killing harmful mollusks on rice and a preparation method thereof. The medicine fertilizer granular formulation contains the following ingredients by total weight: 0.1 percent to 10 percent of niclosamide ethanolamine, 30 percent to 60 percent of carrier fertilizer, 0.5 percent to 3 percent of dispersing auxiliaries, 0.1 percent to 2 percent of retarder, 0.1 percent to 5 percent of attractant and the rest is filling materials. The preparation method of the medicine fertilizer granular formulation is that: the materials are mixed evenly in a closed stirring tank, and then coating granulation, drying, sieving and packaging are carried out. The medicine fertilizer granular formulation of the invention has good control effect of the mollusks on the rice and can not only be used as a pesticide for killing the mollusks on the rice but also can have the effect of increasing production by fertilizing, thus saving time and labor and improving production efficiency.

Description

technical field [0001] The invention relates to a medicinal fertilizer granule for killing harmful molluscs of rice and a manufacturing method thereof. Background technique [0002] In agriculture, snails (commonly known as buffaloes, dry snails), slugs (commonly known as slugs, snails), field snails (commonly known as snails), and snails (intermediate hosts of schistosomes) that harm crops are collectively referred to as harmful molluscs. Harmful molluscs that harm rice are mainly snails and apple snails. The main period of damage is from transplanting to the peak tillering stage of rice. It bites and cuts the main tiller and effective tiller of rice. In the light case, it causes missing plants and broken ridges. In severe cases, large areas of rice are destroyed. Especially in spring, summer and autumn and winter, the weather is rainy, and the damage is more serious when it is wet. [0003] At present, the main pesticides used for the control of harmful molluscs in paddy ...
