preparation example Construction
[0035] The present invention also provides a preparation method of an aerial control preparation for the control of rice field diseases and insect pests, the preparation method preferably adopts the ultrafine pulverization method; specifically, the preparation method includes the following steps:
[0036] 1) Thiofuramide, trifloxystrobin, nitenpyram, chlorantraniliprole, wetting agent, dispersant, thickener, antifreeze, defoamer, viscosity regulator, stabilizer and water in proportion Pre-dispersed into a uniform slurry;
[0037] 2) Sand-milling the above slurry to obtain an anti-flying preparation.
[0038] In the present invention, the sand mill is preferably sanded to a D98 particle size of <5 μm; the sand mill medium is preferably zirconium beads, and the diameter of the zirconium beads is preferably 0.4-1.5 mm.
Embodiment 1
[0041] 12% flying anti-suspending agent, formula by weight percentage: Thiofuramide 3%, Trifloxystrobin 7%, Nitenpyram 1%, Chlorantraniliprole 1%, Polyhydroxy acid sodium salt dispersant 3%, Deca Dialkyl sodium sulfate 2%, xanthan gum 1%, ethylene glycol 3%, polyoxysilane 0.2%, paraffin 0.2%, bentonite 1%, water 77.6%.
[0042] Processed by ultra-fine pulverization method, according to the above ratio, disperse all the raw materials into a homogeneous slurry; then put the slurry into a sand mill and grind it until the D98 particle size is less than 5 μm.
Embodiment 2
[0044] 14% flying anti-suspending agent, formula by weight percentage: Thiofuramide 5%, Trifloxystrobin 7%, Nitenpyram 1%, Chlorantraniliprole 1%, 2-naphthalenesulfonic acid formaldehyde polymer sodium salt 4%, sodium dodecylbenzenesulfonate 3%, magnesium aluminum silicate 1%, urea 3%, silicone defoamer KX-200.3%, cyclohexanol 0.3%, white carbon black 1%, water 73.4 %.
[0045] The preparation method is the same as in Example 1.
