Abstract
The invention provides a seed coating agent of waxy corn, which comprises the following components in percentage by weight: 1 to 2 percent of polyvinyl alcohol, 3 to 8 percent of gum arabic, 0.1 to 1percent of surfactant, 2 to 5 percent of antifreezing agent, 0.1 to 1 percent of defoaming agent, 1 to 2 percent of warning color, 0.5 to 1 percent of thiamethoxam, 0.5 to 2 percent of cypermethrin, 1to 2 percent of carboxin, 0.1 to 1 percent of fludioxonil, 0.1 to 2 percent of chitosan, 1 to 2 percent of potassium fertilizer, and the balance of water. The seed coating agent achieves effective control efficiency to soil insects (cutworms, grubs and the like), stem rot, head smut and aphids, generates obvious control efficiency to diseases and insect damages, and has low dosage. The germination speed of waxy corn seeds is increased by 0.5 day, seedlings grow robustly, the dry fresh weight is increased, and the comprehensive control efficiency of plant diseases and insect pests reaches 90.80 percent; and at the harvest time, the spike length, the spike thickness and the spike grain number are improved compared with a contrast, and the yield of the corn is improved by 10 to 15 percent.
Description
Technical field
The present invention relates to a kind of coating agent for seed, relate in particular to a kind of coating agent for seed that is used for the waxy corn seed.
Background technology
Coating agent for seed is to be used for the dressing plant seed, the material that makes its standardization and commercialization and have film forming characteristics.It is made up of two parts: a part is the auxiliary aid based on film forming agent, comprise film forming agent, suspending agent, antifreeze, preservative, viscosity protectant, diffusant and warning colouration fuel etc., its effect is that formation is the colloidal dispersion system of carrier with water, and film forming, stability, slow release and warning colouration are preferably arranged behind the seed pelleting; The 2nd, active ingredient such as little fertilizer that need add by crop alimentary prescription and insect protected diseases prevention, plant growth regulator, biologic product, insecticide, bactericide, trace element, improve required nutritional condition of seed sprouting and growth of seedling environment, strengthen seed life entity resistance and growth characteristics, improve planting percent, reach the purpose in Qi Miao, full stand, strong sprout, satisfy the requirement of high-yield culturing.
The active ingredient that the corn seed coating agent that uses is gone up in China's production at present mainly is carbofuran, tmtd, Triadimenol, Tebuconazole, but carbofuran is high poison, persistent pesticide, and people, environment, seed are very easily worked the mischief.
Summary of the invention
The object of the invention provides a kind of seed coating agent of waxy corn, by adding biological pesticide, to overcome existing big, big to the environmental hazard shortcoming of corn seed coating agent toxicity, improves the control efficiency of waxy corn damage by disease and insect.
Described coating agent for seed, its percentage by weight component comprises:
Polyvinyl alcohol 1～2%
Gum Arabic 3～8%
Surfactant 0.1～1%
Antifreezing agent 2～5%
Defoamer 0.1～1%
Warning colouration 1～2%
Sharp victory (thiophene worm piperazine Thiamethoxam) 0.5～1%
Handsome seedling (Cypermethrim) 0.5～2%
Wei Fu (carboxin carboxin tmtd thiram) 1～2%;
Fludioxonil and metaiaxy (fludioxonil Fludioxonil Metalaxyl-M metalaxy-M) 0.1～1%
Shitosan 0.1～2%;
Potash fertilizer 1～2%
Water surplus
The preferred Triton X-100 of described surfactant, the preferred ethylene glycol of described antifreezing agent, described defoamer preferably phosphoric acid tributyl, described warning colouration are red or other pigment.
Sharp victory and handsome seedling are insecticide, and Wei Fu and Fludioxonil and metaiaxy are bactericide.
The preparation method of above-mentioned seed coating agent of waxy corn is as follows: with above-mentioned various material weighings appropriate after, elder generation is 1% acetum dissolving with the shitosan weight concentration, again the polyvinyl alcohol water is dissolved, the poly-vinyl alcohol solution that will dissolve and liquid material such as ethylene glycol, defoamer etc. drop in the reactor then, again various granular materials are dropped in the still, the limit edged stirs, and adds water at last and makes used liquid material supply 100 parts, gets final product.
The present invention is used various active components, underground insect (cutworm, grub), aphid, stem rot, head smut are all reached the effectively preventing effect, reach the pesticide-germicide dual purpose, disease, insect pest have all been produced tangible control efficiency, employed dosage is lowest dose level, even be lower than label recommendation using dosage, thereby reduced cost.
Especially need to prove, the present invention is in prescription, having added with shitosan, potassium is " Shangke No.1 " (own product) of main component, and shitosan had both had film forming preferably, can regulate growing of milpa again, improve the immunity of plant, improve the nutritional quality of plant, regulate the activity of the degeneration-resistant metabolic enzyme of plant, strengthen the resistance of plant, adapt to its growth in adverse environment, can be developed into to a kind of biological pesticide and use.Show as by testing mainly, behind the dressing, corn seed is sprouted the 0.5d that speeds up, growth of seedlings is more sturdy, and dry weight and fresh weight of plant seedlings increases, and the control efficiency of waxy corn damage by disease and insect reaches 90.80%; According to all increasing, maize yield has improved 10-15% to thick, the grain number per spike comparison of when results spike length, fringe.By finding that relatively after " Shangke No.1 " added potassium element, it is hard that the plant cane becomes, lodging tolerance increases, in certain effect of having played of control corn stalk rot disease.The applicant thinks that the interpolation of potassium ion and shitosan has more excited the effect of other four kinds of active components, makes milpa growing point, spire, the interior glucide of the tip of a root synthesize and strengthen that resistance improves, and plays a kind of synergy.
In sum, more than various active components both brought into play itself action effect, cooperatively interact again, other active components are produced synergy, disease, the insect pest of corn produced the better prevention effect, improved corn yield, produced synergistic effect.
