Description
Invention field
The present invention relates to agriculture field, be specifically related to a kind of agricultural agent composition.
Background technology
In order to give full play to the effect of insecticide, bactericide, miticide, weed killer herbicide and growth regulator, the consideration of the efficiency while scattering according to agricultural chemicals and safety aspect, in pesticide producing, all will add suitable agricultural surfactant, that surfactant has played in preparation processing is wetting, the effect of dispersion, emulsification, solubilising, spread, froth breaking.After being in use sprayed onto on target, there is following effect: 1. can expand droplet effective contact area, dwindle the air gap between solution and blade surface, the anti-diffusibility of blade cuticula is declined; 2. the agricultural chemicals in dissolve deposits, prevents from or delays crystallization in sediments forming; 3. dissolve or destroy cuticular wax, when agricultural chemicals infiltrates cuticula, as cosolvent or stabilizing agent, working; 4. promote pesticidal solutions to absorb by pore and space between cells stable; 5. activate agricultural chemicals and enter plant leaf blade approach, strengthen cell leakage; 6. infiltrate rapidly cuticula, affect solvability in cuticula, cause the infiltration of surfactant and active principle; 7. play wetting, spread effect, prevent that drop is withered rapidly, extend soak time.
The surfactant with good infiltration and scalability that some are new constantly occurs, as azone, thiophene ketone and organic silicon surfactant, these surfactants can reduce the surface tension of pesticide spray solution greatly, strengthen liquid at moistening, adhesion and the plate-out ability energy of plant surface or sick polypide table, increase spray liquor coverage rate; Promote that spray liquor absorbs fast, thereby improve drug effect.Organic silicon surfactant even can make the absorption ratio of some agricultural chemicals reach more than 85%, and is transient absorption, and this has not only reduced volatilization and the photodissociation of medicament, and has avoided the drip washing of rainwater.Even but so good surfactant can not be satisfactory in some application effects.
The composition of different performance agricultural agent can improve performance and the range of application of agricultural agent, the invention of this respect is a lot, and CN102271520A has announced a kind of composition that contains oxyalkylated polyol ester, oxyalkylated alkyl or alkenyl oligosaccharides glycosides, fatty acid or salt.CN1887082A has announced a kind of herbicide assistant, by mineral oil and/or vegetable oil or esterified vegetable oil, it is raw material, the auxiliary agent that coordinates nitrogenous fertilizer, surfactant to form, can improve herbicide effects, increases deposition, spread and the absorptive amount of weed killer herbicide on plant leaf blade.But these surfactants are all to take to enter plant corpus as research object by blade, woody plant, particularly on tall and big arbor species, there is very large restriction.
Along with the development of China's ecological construction and the raising of living standards of the people, orchard area, afforestation area and forest coverage all increase sharply, and Epidemic Disease of Forest also rolls up simultaneously.The control of Epidemic Disease of Forest is compared and is very different with vegetables with crops: forest tree height is large, conventional spraying apparatus can not be sprayed onto tree crown, both used high-tension apparatus, can not guarantee blade even medicine, control efficiency is poor, have the liquid of 50% left and right to descend slowly and lightly simultaneously and cause waste and environmental pollution in aerial with ground, while water requirement is larger, in some water-deficient areas, cannot apply; Forest has many limb diseases and pests, and as rot, ring spot, canker, longicorn, flatheaded borer, bark beetle, coccid etc., these damage by disease and insect must just can be prevented and treated by trunk medication.Trunk medication at present mainly contains following several mode: trunk direct drug injection, injecting drug use, filling root.Fill with root contaminated soil and underground water, a large amount of medicaments are by adsorption by soil, and cost is higher.Injecting drug use is a kind of good method, dosage is little, effective, but need special-purpose equipment, cost is higher, need to, at tree body upper drill hole, to tree body, injure larger simultaneously, particularly year after year medication meeting to make to set body riddled with gaping wounds, these wounds may become the new route of entry of some diseases and insect pest.To some trunk borers, adopt turunda in burrow, insert the method that poison is signed, because trunk is tall and big, burrow that can not be all can guarantee medication, has increased the risk of operating cost and operation due to work high above the ground simultaneously.The shortcoming of trunk direct drug injection maximum is because trees have very thick bark, bark is not have lived tissue, can not active absorption medicament, medicament must be penetrated into phloem and just can be absorbed, but it is just dry often not wait medicament to be penetrated into phloem, lose infiltration capacity, therefore direct drug injection absorption ratio is very low, anti-heterodyne, in order to improve control efficiency, conventionally adopt the Lao Pi that strikes off trees, after coating, wrapping up Polypropylence Sheet prevents from drying up, although improved preventive effect, but operating efficiency is extremely low, to a small amount of trees treatment, can manage it, it is unpractical in this way that a large amount of forests are treated.On Evergreen garden plant, rossing has affected the overall appearance of trees simultaneously.
