Description

A kind of assistant composition processing plant
Technical field: the present invention relates to a kind of assistant composition processing plant, its preparation method and purposes. The present invention also relates to the composition of above-mentioned assistant composition and exogenous chemical substances, and wherein exogenous chemical substances comprises weedicide, sterilant, sterilant, growth regulator and stem leaf spraying fertilizer.
Background of invention:
Stifling, the stomach toxicity that pesticide preparation has when applying, interior suction and tag etc. effect with add auxiliary agent after for the sprawling of target, permeate, the usefulness such as Zhan Zhe, deposition closely related. In fact the just drift evaporation that do not play a role of the agricultural chemicals of major part in atmosphere, is lost in soil, only have an appointment 30% deposit medicament on target, its drug effect can be played. In target the wax of the oiliness on plant leaf surface and wax and insect epidermis all can affect the sprawling of liquid, permeate, Zhan Zhe, deposition. And the diluent surface tension that tensio-active agent makes pesticide preparation reduces, reducing with the contact angle of target, wetting seepage force strengthens, thus improves drug effect. Make used additives if inappropriate, it would be possible to make liquid settling be significantly less than 30%. There are some pesticide original medicines soluble in water, it is possible to be mixed with aqua, and the stability of its diluent also can be qualified when not adding assistant, but wetting infiltration, plate-out ability are poor, so still needing to add auxiliary agent. The definition of aqua is the aqueous solution preparation of effective constituent and auxiliary agent by China's " pesticide formulation title and code national standard ". The aqua not adding auxiliary agent does not obviously meet the definition of this standard, and auxiliary agent is to the importance guaranteeing pesticide preparation usefulness as can be seen here.
In CN1545881A Chinese patent application, disclose a kind of glyphosate isopropylamine salt water solution builder, can use with glyphosate isopropylamine salt water solution mixture. It is water and the composition of tensio-active agent tallow amine Soxylat A 25-7, Oleum Cocois diethanolamine ester, amine ether APG, empgen BB, anhydrous sorbitol and initiator ammonium sulfate, the weight percent of each component is: tallow amine Soxylat A 25-7 40-50%, Oleum Cocois diethanolamine ester 10-20%, amine ether APG 10-20%, empgen BB 10-20%, anhydrous sorbitol 5-10%, ammonium sulfate 2-5%, surplus are water, and the summation of each component is 100%.
There is raw materials cost height in the auxiliary agent of this patent, and the problem that the ratio added in ammonium glyphosate aqua is higher.
In CN1147226C Chinese patent, by to volatile oil, preferably the deregulated volatile oil of EPA is added sodium lauryl sulphate or Yelkin TTS, the material of independent non-activity or relative inactive is made to produce the acceptable insecticidal properties of business, and without the need to using the not welcome agricultural chemicals to the toxic effect of people and pet, obtain the sterilant of a kind of synergy. This insect-killing composition, the synergistic agent comprising volatile oil and selecting from the group being made up of sodium lauryl sulphate and Yelkin TTS, according to the combination of insecticidal synergistic ratio as basic effective ingredient.
The object of this patent is to be combined with specific volatile oil, makes the volatile oil without insecticidal activity have the effect killing worm, and can not be applicable to separately and generally Multiple Pesticides composition.
Summary of the invention:
Using and waste problem to solve the excessive of agricultural chemicals in prior art, the present invention provides a kind of assistant composition processing plant, its preparation method and purposes. The assistant composition of the present invention can be used in combination with weedicide, sterilant, sterilant, growth regulator and stem leaf spraying fertilizer. The assistant composition preparation technology of the present invention is simple, and actual effect is good, is that the weeds to some control difficulty and insect pest have and show the builder of prevention effect.
The assistant composition that the present invention processes plant can strengthen the drug effect of external source active substance, it is to increase the biological activity of weedicide and reduce drop drift, penetration enhancement conduction and strengthen weedicide to the anti-effect of weeds. Component in assistant composition of the present invention is the material of natural existence, can be absorbed by plant pericarp, strengthens the resistance against diseases of fruit. Its hydrophilic group can keep fruit skin moistening, prevents germ from encroaching on, and suppresses pathogen growth breeding, plays sterilization functions, extends the fruit freshness preserving phase; Prevent and treat the effect of the diseases and pests of agronomic crop such as vegetables, paddy rice in addition in addition. So the present invention is used in does not only penetration enhancement and conduction on object, also nourish crop and melon and fruit. Because it derives from green plants, there is good affinity with plant, therefore, than petroleum-type mineral oil, the security of various sensitive crop and crop critical porion is higher.
The present invention in process that sprays at general agricultural chemicals has good perviousness, extendability. As a kind of agricultural spray adjuvants, it can allow the agricultural chemicals sprayed more easily permeate and stick to plant surface, absorbs and is washed down sooner and not easily; Meanwhile, good extendability makes its only need very little spray amount just can obtain desirable spray effect, can save when spraying insecticide reach 50% use water. So both can cut the waste, again reduce the pesticide volume being lost in soil and groundwater, and then the pesticide residue decreased in environment. It has complied with the trend of environmental protection type agricultural chemical development.
