Abstract

The granular agricultural chemical for underground pests, seedling pests, soybean borer, aphis, etc. is made of sand (carrier), phorate (5.1%), diatomite as absorbent (5%), gypsum as coating agent (3-10%), water (1-3%) and iron oxide as colouring agent (0.3-0.5%) and features low cost, safe and reliable effect and easy application.

Description

Gypsum dressing 5% thimet granule

The invention belongs to a kind of granula type agricultural chemicals.

Along with improving constantly and the development of agricultural commodity production, high yield, high-quality, comprehensive assessment target that high benefit is agricultural production and technology of living standards of the people.Realize this goal, except that improved seeds and balance fertilizing, the science applying pesticides is important means.Thimet is a kind of high-toxic pesticide, for the soil insect of field crop, seedling stage insect such as insect, soybean pod borer, budworm have the extremely strong ability of killing.Poison in order to prevent that people, animal from contacting, and can make the medicine slowly-releasing,, can reach the efficacy of a drug of kill pests, can prolong the purpose of effective drug duration again, adopted the dressing way, released a kind of paraffin dressing 5% thimet granule in recent years to guarantee dosing time.

Paraffin dressing 5% thimet granule manufacturing prescription is:

River sand is made carrier, and former medicine of 5% thimet and diatomite (adsorbent) are wrapped in mixer on the sand of carrier river equably, uses the paraffin dressing, and does coloring agent with red Zhu.The critical defect that this formulation exists is the price height, has increased cost of crops and the financial burden that the peasant purchases medicine.

Purpose of the present invention provides the gypsum dressing 5% thimet granular agricultural chemical that a kind of price is low, the drug effect phase is long.

The prescription of gypsum dressing 5% thimet granule is:

1 ton of gypsum dressing 5% thimet granule is prepared less than the former medicine 5.1% of river sand 76.4%～83.2%, the thimet of 1.6mm, diatomite 5%, water 1～3%, gypsum (calcium sulphate) 3～10%, iron oxide 0.3～0.5% (percentages) with diameter.Wherein gypsum is that seed coating medicine, iron oxide are coloring agents.

Main points of the present invention are to replace paraffin to make seed coating medicine with gypsum, replace red Zhu to make coloring agent with iron oxide.Use the gypsum dressing, than using the paraffin dressing, 5% thimet granular agrochemical per ton can reduce by 80～100 yuan of prices.Therefore, apply gypsum dressing 5% thimet granular agricultural chemical, not only has good kill pests performance, improve crop yield, and can alleviate peasant's burden widely, and reduce the crop cost, use in the experiment in that the large tracts of land crops are actual, received good effect, welcome by the peasant.Gypsum dressing 5% thimet granule is a kind of high-toxic pesticide, the low novel form agricultural chemicals that poisons processing.

Yet, for the development of new seed coating medicine, the our factory has carried out a large amount of formulation screenings, has determined with the gypsum to be seed coating medicine after research and the experiment work, and through more than 2 years, the prescription and the production technology of gypsum dressing 5% thimet granular agricultural chemical that tens of tests are just perfect.

Gypsum dressing 5% thimet granule production technology (summary)

1, with the washing of river sand, after air-flow or the dry processing of drum process, use bolting, select diameter to make carrier less than the clean river sand particle of 1.6mm;

2, by the prescription requirement river sand, the former medicine of thimet, diatomite are put in the mixer and mixed, and evenly be bonded on the sand of river, add entry by the prescription requirement then, add the seed coating medicine gypsum again, the colouring agent iron oxide, dressing in cylinder carried out the dressing molded-in-color in about 40～60 minutes, and in vibra shoot, evenly shake, be finished product through packing.

Embodiment:

Produce 1 ton of gypsum dressing 5% thimet granule prescription:

Diameter is less than 1.6mm river sand 83.2%, the former medicine 5.1% of thimet, diatomite 5%, water 1.2%, gypsum 5%, iron oxide 0.5%.

Claims

1, gypsum dressing 5% thimet granular agricultural chemical, it is characterized in that this agricultural chemicals effluent sand, the former medicine of thimet, diatomite, water, gypsum, iron oxide make, the proportioning (percentages) of 1 ton of gypsum dressing 5% thimet granular agricultural chemical is: river sand (diameter is less than 1.6mm) 76.4～83.2%, the former medicine 5.1% of thimet, diatomite 5%, water 1～3%, gypsum 3～10%, iron oxide 0.3～0.5%; Its best proportioning is: river sand 83.2%, the former medicine 5.1% of thimet, diatomite 5%, water 1.2%, gypsum 5%, iron oxide 0.5%.
