Description
This divisional application is based on Application No. 200580050058.6, and the applying date is on April 25th, 2005, denomination of invention
Divisional application for the original Chinese patent application of " for the Fungicidal aqueous compositions of seed treatment ".
Technical field
The present invention relates to Aquo-composition, it is related to the preparation of such compositionss and resists plant using such compositionss
The method of thing pathomycete.The described Aquo-composition of the present invention resists the protection of fungal disease in plant propagation material such as seed
In there is specific application.
Background
It is broad practice of for preventing and treating phytopathogenic fungi using synthesis of antifungal agents in crop.This practice obtains height
The business success of degree, as it have been shown that such preventing and treating can improve crop yield.Antifungal can directly apply prior to seeding
It is overlying on plant propagation material (as seed) and/or apply for foliar application or ditch dug with a plow.
Seed treatment is applied on the crop of a large amount of species to control the nuisance of a large amount of species.It is usually used at seed
Managing to guarantee the foundation of the consistency criterion of the protection resisting soilborne disease and insecticide.The seed treatment of system can carry
For for the airborne disease of specific early stage in season and the conventional spray leaf antifungal of insecticide or replacing of insecticide
In generation, selects.
Generally, for three kinds of reasons using fungicidal seed treatment: (1) preventing and treating causes seed decay, moisture regain, rice shoot withered
The organism (pathogen) of the soil-borne disease withered, the fungal pathogens that (2) preventing and treating the surface of the seed is propagated cause greatly as those
Wheat and loose smut of oats mildew, the granule disease of Semen Tritici aestivi, the black speck of grain, and the Flos Carthami rust (safflower rust) of seed dispersal；
(3) the fungoids loose smut of the fungal pathogens of internal control seed dispersal such as corn.
Seed treatment antifungal has various formulation forms: mainstream body (df), fluid liquid (lf), true liquid (tl),
Cream (ec), powder (d), wettable powder (wp), suspended emulsion (se), water dispersible granule (wg) and other.Some of them are
Registration is used only for applying machine using the business of closed enforcement system, and other are as powder, slurry agent, water soluble bag
Agent, or liquid i.e. with preparaton can easily be used for farm application (on-farm use).
Due to being appropriately carried out processing or processing substantial amounts of seed and need professional equipment it is often desirable to have business-like
Seed treatment.Significant concern for commercialization datatron is to ensure that the equipment on the active delivery of appropriate amount to seed
Performance.For the more modern antifungal of the material requiring small amount, this becomes, and more important (as little as 1g active component is every
The seed of 100 parts of weight).
Routinely, many seed treatment materials can also be used for farm application.These are known as hopper bucket (hopper-box)
Or sowing bucket (planter-box) is processed, when wherein liquid adjustments or preparaton is dried is turned by spiral from transport storehouse
(auger) it is applied to seed when delivering to sowing bucket.With very conventional approach implement plant before planting by a moment for these preparatons
Subprocessing is to agglomerate seed.Conventional dried generally use by process chemicals adhere to Pulvis Talci on seed or
Graphite is prepared.Conventional liquid material bucket is processed generally useful as rapid-curing cutback preparaton.Under any circumstance, in order to obtain any kind
The maximum benefit of subprocessing preparaton, needs to coat well seed.
However, when attempting to process seed, being difficult to obtain the cladding completely of seed.For example, dry preparaton may can not connect
Expose workers to Fungicidal active ingredient with being subject to.Some liquid adjustments may become heterogeneity in storage, so that granularity
Or viscosity can not keep constant.In addition, it may create problem such as unacceptable drying time, the material in seed processing machine
Material is formationed, low seed mobility, the seed cladding of deficiency and dust removal (dust-off) antifungal from seed prior to seeding.
As a result, operation becomes biological effect that is difficult and reducing seed treatment.
There is a need in the art for new alternative liquid fungicidal seed treatment compositions, it is effectively applied to business
Seed-treating apparatus and farm seed-treating apparatus.
