Abstract
The agricultural chemical preparations that can on the water surface, move and sprawl, its composition is the core that particle is formed, and its each apparent specific gravity is coated with the agricultural chemicals active matter less than 1 on it, also be coated with a kind of material, the interfacial tension between air and the water reduced by means of oily mater.
Description
The present invention relates to the agricultural chemical preparations that can on the water surface, move and sprawl,, still can move and spread on the whole water surface, therefore, active substance can be discharged in the water in rice field quickly and evenly even be applied on the local water surface.
General its form of the agricultural chemical preparations of using in the rice field has dust agent, particle, wettable powder, mobile concentrating agents, water solube powder, water-soluble liquid, emulsion or the like.
Recently, labour and environmental protection are quite paid attention to saving in the present technique field, so use the graininess preparaton being on the increase.But under the situation of using granule, the diffusion of contained active matter or distribution speed are still limited in each.The result is that when using these preparatons, agricultural author has to often in the rice field.
In recent years, save the labour during people's strong request dispenser, so urgent insecticide-applying way of wishing that development is following, for example low dose of dispenser (dispersion volume is a per hectare 30-10 kilogram), mechanical type dispenser and " big part (the jumbo) " preparaton that is used to throw dispenser.
The big part preparaton of throwing dispenser just stood on the ridge that the fritter rice field forms medicament thrown into fritter Tanaka being used to of having developed, and its active matter is evenly distributed in the water in rice field.
More detailed saying, the test that these preparatons carried out is to use the tablets, spherical dose of weight 100 or 50 grams, the forms such as particle of filling, formulated together active matter and aqueous solvent and/or foaming agent in these parts, they are dispersed in the water in rice field easily.
But, such preparation is compared with conventional formula granule, and in fact the former needs the longer time just active matter to be dispersed in the water in rice field, otherwise they can not distribute equably all over the monoblock rice field area, consequently make the effect performance insufficient, or cause dunsiekte.
As above-mentioned, the so-called big part preparaton that is used to throw dispenser originally is intended to save the labour, but the difficulty of being met is to be difficult to make active matter to scatter fast and equably in paddy field water either, provides solution so this area urgently is required to be this difficult problem.
At an above-mentioned difficult problem, the present inventor has successfully finished the present invention through going deep into broad research, and the Agrotechnical formulation that use can be moved when floating on the water surface in rice field, thereby can disperse equably and spread all over the whole surface in this piece rice field.
Therefore, the present invention relates to the agricultural chemical preparations that can move and sprawl at the water surface, its composition is the core that particle is formed, its each apparent specific gravity is less than 1, be coated with the agricultural chemicals active matter on it, also be coated with a kind of material, the interfacial tension between air and the water reduced by means of oily mater; Or this preparaton wrapped up with water-solubility membrane, be bundled into every 10 to 200 gram; Or, make for example plate-like, column, positive parallelepiped and cube this preparaton shaping.
(annotate: above-mentioned apparent specific gravity is different with bulk specific weight, and the former is that the quality (gram) with a particle with internal pore space is a denominator, is that denominator is tried to achieve with the volume that comprises this internal pore space.）
Say that more specifically in preparation of the present invention, this surfactant is not on the whole surface attached to particle cores, but is attached on its part surface, so the interfacial tension that changes with direction takes place in the water in the external world.Therefore, the preparation that is applied in the rice field moved at the water surface of resistance less than the inside of water before this, thereby the effect that preparation disperses to side direction takes place, and active matter dissolves to water from water surface then, is dispersed throughout this piece field until them.
That is to say that mode of the present invention is not that point from the surface, rice field disperses, but from the whole area generation peptizaiton in this piece field, thereby active matter thoroughly and is effectively distributed.
The person of advancing, because self exclusive mobility of this preparaton, can be in the some dispenser in a rice field, thus realize processing to all surfaces.
When throwing preparaton of the present invention in the rice field, single preparation granules moves with at random direction at the water surface, because contained interfacial tension reducing agent is dissolved in the water in the preparation, the result makes those particles scatter quickly and evenly at the rice field water surface.
That is to say, when preparation moves on the water surface, the agricultural chemicals active matter is disperseed and be dissolved in the water.Because to disengage active matter from preparaton rather quick, even its particle cores is to stay on the water surface and owing to wind-force drifts about, that in a moment active matter disengage already so that any inhomogeneous broadening effect can not take place, so can avoid taking place the dunsiekte problem.
Preparaton of the present invention is considered from its carrying operation and dispersibility, serves as preferred with the graininess formulation, but if consider to have flow behavior in the water, then can be mixed with and spread dust agent, fine grained, tablet or the like.
Preparation of the present invention can be with the former state preparation to jettisoning or to use giver by hand.Also can be packaged in them in the water-soluble bag, bag is thrown in the rice field.In addition, also can use the preparation of tablet and so on.Preparation light pressure the in mould that is about to scheduled volume forms.
