Abstract
The present invention relates to floatability and can spread insecticide tablet formulation, relate to the method for the preparation of this preparation, and relate to the method for being carried out injurious insect control by spraying.
Description
Invention field
The present invention relates to water floating and diffusible tablet, relate to the method for this tablet of preparation, and relate to by this tablet being applied to insect or insect location controls or resists the method for insect.Can from ridge to paddy field application by throwing them this tablet, and need not paddy field be entered into.In addition, this tablet has the diffusibility being better than conventional agrochemicals preparation (such as particle), and therefore can diffuse through longer distance from application position and show insecticide effect.Therefore, this tablet is easy to use and causes saving labour.In addition, therefore this tablet not airborne dust is safe to peasant and to contiguous crop.By by sheeting equipment, make water floating carrier, water-solubility carrier, etc. mixture be configured as tablet to prepare tablet of the present invention.
Background of related
In the prior art, typically agrochemicals particle is used with the ratio of 3kg/10 are.These particles are heavy and inconvenience for peasant, particularly when he must enter into paddy field to use these particles.Even if peasant can use sprayer to use these particles, the floating dust kicked up from these particles to float to contiguous crop and causes phytotoxicity.In addition, rural population are just aging.Therefore, it may be necessary exploitation for laborsaving correlation technique (such as so-called large granula (jumboformulation)) with make injurious insect control easier for the instrument of agricultural chemicals of spraying.
Therefore, it has been developed to the particle can used by the ratio of 1kg/10 are.But in order to use described particle, peasant still needs to enter into paddy field.In addition, they can not be applied to broad area equably, and this uneven the using of particle causes phytotoxicity.In order to overcome these problems, developed in recent years effervescent tablet, water floating particles (" rising particle ") and water floating and diffusible particle.
Conventional effervescent tablet is as follows.A kind of herbicidal composition for being dispensed onto the stabilisation in paddy field and use the herbicidal methods of this weed killer herbicide to be disclosed in Korean Patent Application No. 10-2000-0066923; And manufacture and use the method for laborsaving effervesce agrochemical composition to be disclosed in Korean Patent Application No. 10-2005-0128960.Effervescent tablet comprises a kind of organic acid and a kind of alkali, and they, reacting each other to produce carbonic acid gas with during water-wet in paddy field, make active component to be disperseed thus.But due to these characteristics, if effervescent tablet is exposed to moisture between manufacture or storage life, effervescence properties dies down, and this can cause the crop plants toxicity in paddy field.
Conventional " rising particle " (" being packaged in parcel ") is as follows.There is the water surface and send out the agrochemicals particle of behavior and manufacture method is disclosed in Korean Patent Application No. 10-1997-002003; Floating solids formulation of insecticides is disclosed in Korean Patent Application No. 10-2001-7012786; And to throw into agrochemical formulations in paddy field (it be by with water-solubility carrier by the granulation of agricultural active composition and be packaged in preparation in the parcel of water-solubility membrane) be disclosed in Korean Patent Application No. 10-1999-0005669.When by with water-solubility membrane manufacture and the parcel comprising the particle of 25g or 50g is applied to paddy field time, first this parcel sinks.Then, once water-solubility membrane is dissolved, these particles rise to the water surface and spread all over paddy field and show biology effect.The dissolution time packing the water-solubility membrane of these " rising particles " depends on the character of water-solubility membrane and the water temperature of the degree of polymerization and paddy field.In addition, water-solubility membrane has viscous characteristics.Therefore, when the dissolution time in water becomes too slow, undissolved film stops particle to rise to the water surface---and this can cause the localization of the active component causing crop plants toxicity.In addition, usually due to working environment, the hand of peasant is spontaneously wet out by water, and so wet hand clings water-solubility membrane, and therefore film is easy to be torn.
Conventional water floating particle is as follows.Diffusible granular insecticide composition is disclosed in Korean Patent Application No. 10-2006-7001630 equably; Desinsection particulate composition for paddy rice is disclosed in Korean Patent Application No. 10-2006-0075641; Water floating and diffusible granular agrochemical preparation and manufacture method thereof are disclosed in Korean Patent Application No. 10-2006-0121940; And be disclosed in Korean Patent Application No. 10-2001-7008584 for the method for the floating Pesticidal combination of paddy field, its Application way and production said composition.But these floating particles are all light separately, therefore can not by far throw, and method spended time for the preparation of them is long and more complicated than the particle of routine.
