Description
This divisional application is 200580050058.6 based on application number, and the applying date is on April 25th, 2005, and denomination of invention is the divisional application of the original Chinese patent application of " Fungicidal aqueous compositions for seed treatment ".
Technical field
The present invention relates to Aquo-composition, relate to the preparation of such composition and use such composition to resist the method for phytopathogenic fungi.Described Aquo-composition of the present invention has concrete application in plant propagation material is as the protection of seed antagonism fungal disease.
Background
In crop, use synthesis of antifungal agents to be broad practice to prevent and treat phytopathogenic fungi.This practice obtains the business success of height, because shown that such control can improve crop yield.Fungicide directly can be coated on plant propagation material (as seed) prior to seeding and/or use for foliar application or ditch dug with a plow.
To control the nuisance of a large amount of kind on the crop that seed treatment is applied to a large amount of kind.Usual use seed treatment guarantees the foundation of the consistency criterion of the protection resisting soilborne disease and insect.The seed treatment of system can be provided for early stage airborne disease and the conventional spray leaf fungicide of insect or the alternative of insecticide in specific season.
Usually, fungicidal seed treatment is used: (1) prevents and treats the organism (pathogene) of the soil-borne disease causing seed decay, moisture regain, rice shoot to wither for three kinds of reasons, (2) fungal pathogens preventing and treating the surface of the seed propagation causes barley and loose smut of oats mildew, the granule disease of wheat, the blackspot of grain as those, and the safflower rust of seed dispersal (safflower rust); (3) fungal pathogens of internal control seed dispersal is as the fungoid loose smut of cereal.
Seed treatment fungicide has various formulation forms: master stream body (DF), fluid liquid (LF), true liquid (TL), missible oil (EC), pulvis (D), wetting powder (WP), suspended emulsion (SE), water dispersible granula (WG) and other.Some of them are registered as only for using the business of closed implementation system to use machine, and other are as pulvis, slurry agent, the agent of water soluble bag, or liquid namely can easily for farm application (on-farm use) with preparaton.
Owing to suitably implementing process or processing a large amount of seeds and need professional equipment, often wish business-like seed treatment.Significant concern for commercialization processor guarantees the active delivery of appropriate amount to the equipment performance on seed.For the comparatively modern fungicide of the material required very in a small amount, this becomes more important (being low to moderate the seed of the every 100 parts of weight of 1g active component).
Routinely, many seed treatment materials also can be used for farm application.These are known as hopper bucket (hopper-box) or sowing bucket (planter-box) process, are applied to seed when wherein liquid adjustments or dry preparaton are turned when (auger) delivers to sowing bucket from transport storehouse by spiral.These preparatons implement seed treatment on agglomerate seed with very conventional approach before planting a moment.Conventional drying process generally uses and process chemicals is adhered to talcum powder on seed or graphite preparation.Conventional liquid hopper bucket process generally can be used as rapid-curing cutback preparaton.Under any circumstance, in order to obtain the maximum benefit of any seed treatment formulation, need coated seed well.
But, when attempting process seed, be difficult to obtain the completely coated of seed.Such as, dry preparaton may unacceptably make workman be exposed to Fungicidal active ingredient.Some liquid adjustments may become heterogeneity in storage, can not keep constant to make granularity or viscosity.In addition, issuable problem as unacceptable drying time, material in seed processing machine formed, low seed mobility, not enough seed be coated and prior to seeding from dust removal seed (dust-off) fungicide.As a result, operation becomes difficulty and reduces the biological effect of seed treatment.
Need new alternative liquid fungicidal seed treatment compositions in this area, it is effectively applied to business seed-treating apparatus and farm seed-treating apparatus.
