Description
Technical field
The invention belongs to agricultural technology fields, are related to a kind of fast appraisement method of agricultural chemicals formula.
Background technique
Most of agricultural chemicals can not be used directly, it is necessary to which being processed into the preparation with certain form could make in field
With.By taking pesticidal preparations as an example, the physical and chemical stability of preparation is usually first solved at the initial stage of research and development of products, development obtains physics and chemistry
After the pharmaceutical formulation of performance qualification, then the practical application effect of preparation is studied, usually carries out indoor bioassay first, filter out
After more excellent formula, then field control effectiveness test is carried out, field control effectiveness test is that Formula Development ensures its applications well effect in the process
An essential link.But indoor biometrics experiment can not perfect forecast pesticidal preparations Field information actual effect, this
The number and test site for usually requiring to increase field control effectiveness test are allowed for, is such as wanted in the pesticidal preparations registration test in China
It asks to the field control effectiveness test for newly registering 2 years four ground of product progress.When enterprise carries out new-product development, field efficacy is carried out
The number of test is then more.Field control effectiveness test is carried out to need suitable weather conditions, be suitble to carry out disease, the worm, crop smothering of test
A situation arises；The repeatability of field control effectiveness test is bad, needs to carry out large sample test, obtains trend according to statistical analysis principle
Property as a result, required human and material resources are larger, and a situation arises is limited by season, weather, disease, worm, crop smothering.Agriculturalization
One free-revving engine of product Formula Development is exactly the bioactivity for optimizing effective component, improves effective component and is transmitted to prevention and treatment pair
As the ratio with Target crops, and field trial causes the R&D cycle to increase because of its intrinsic disadvantage；Field trial can screen
Field control effect is preferably formulated out, but from the result of field trial without it is legal, quantitatively obtain influence field trial effect
The factor of fruit, it is difficult to which targetedly adjustment formula, research staff often can only rule of thumb be adjusted formula, cause in this way
Formula adjusts the guidance of no scientific theory and data, while also affecting the efficiency of Formula Development.The present invention is based on insecticide,
Herbicide, fungicide, foliar fertilizer, the plant growth regulator mode of action and its preparation medical fluid and controlling object in use
With the interface interaction process of Target crops, a kind of method that can be formulated superiority and inferiority with Fast Evaluation agricultural chemicals is established, it is this
Method can reduce the number of indoor biometrics experiment, field control effectiveness test, help to reduce product development cost, shorten research and development week
Phase reduces the blindness of formula research and development.
Although forefathers have done much in terms of medical fluid physicochemical properties such as surface tension, viscosity and the correlation of drug effect
Research: as Lu Xiangyang et al. has studied the correlation (Lu Xiangyang of several herbicides medical liquid surface tension, blade face contact angle and drug effect
The correlation research Pesticide Science journal of equal several herbicides medical liquid surface tension blade face contact angle and drug effect, 2002,4 (3):
68-71.)；Zhang Libin et al. has studied influence (the medical fluid table such as Zhang Libin of medical liquid surface tension and viscosity to glyphosate drug effect
Face tension and viscosity are on the influence of glyphosate drug effect and its mechanism study plant protection, 2011,37 (5): 160-163), but this
A little researchs are studied from the relationship of the individual parameters such as surface tension, contact angle and drug effect, can not be come as universal method pre-
The practical application effect for the side of being measured, as linear dependence or simple positive correlation is also not present in the value and drug effect of its surface tension
Property or negative correlation.The present invention is then by apparent free energy, deposition, adhesion strength, surface tension, contact angle, the droplet uniformity, infiltration
The interface interactions parameter such as permeability is integrally investigated, according to Insecticides (tech) & Herbicides (tech), fungicide, foliar fertilizer, plant growth regulator
The mode of action and its preparation the interface interactions of medical fluid and controlling object and/or Target crops is realized to agriculture in use
With the Fast Evaluation of chemicals formula, the mode of action of 1. effective components is specifically included that.The mode of action of effective component is generally divided
Medical fluid is paid the utmost attention in the deposition on Target crops blade face for the effective component with systemic action for absorbability and contact toxicity
Amount, spreading area are then accounted for as secondary index；For the effective component with contact toxicity, then pay the utmost attention to sprawl
Area, the physical quantity of determination influences spreading area, such as surface tension, contact angle.2. Target crops blade face characteristic.Main measurement target
It is denoted as the apparent free energy on object blade face, the surface tension of medical fluid is necessarily less than the apparent free energy on blade face, and medical fluid could be in target
Crop blade face carries out wetting and spreading.3. medical fluid interfacial characteristics.Main measurement medical liquid surface tension, effect of surface tension are atomized equal
Evenness and droplet size, this process can regulate and control droplet size, the uniformity.4. solid-liquid interface mechanism.This mistake
The static process that journey is related to includes static contact angle, the droplet uniformity；Dynamic process is related to adhesion strength, dynamic contact angle, drop
Retraction rate, the deposition of this process and medical fluid on Target crops blade face are closely related.The present invention is based on insecticides, weeding
Agent, fungicide, foliar fertilizer, the plant growth regulator mode of action and its preparation in use medical fluid and controlling object and/
Or the interface interaction of Target crops, by physical quantity of the measurement during each, it is suitable to be chosen according to the effective component mode of action
Parameter be ranked up, assay, can quantitative comparison formula in medical fluid from spraying apparatus to Target crops or controlling object
The height of transmission efficiency can be researched and developed, be subtracted with scientific guidance agrochemical formulation formula to evaluate the superiority and inferiority of pharmaceutical formulation
The number of few field control effectiveness test, the Field information effect for improving preparation have the meaning of highly significant, help to reduce
Product development cost shortens the R&D cycle.It is agricultural chemicals below in controlling object and the tool of the interface interaction of Target crops
Body explanation illustrates thought of the invention so as to clearer.
Agricultural chemicals are in controlling object and the interface interaction of Target crops:
Agricultural chemicals are normally prepared as preparation, generally require and use after being configured to dilution, and dilution is from application equipment
To reach controlling object and Target crops will undergo a series of transmittance process, specifically include that 1. from preparation to can be used
The twice dispersing of dilution and the dispersion transmittance process of atomization, research shows that about 5% can be caused due to evaporating, emitting, dripping or leaking of liquid or gas etc.
Transmitting loss；2. the space transmittance process of controlling object and Target crops is reached from droplet, research shows that due to droplet evaporation, drift
The reasons such as shifting, can cause about 20% transmitting to lose；3. droplet reaches controlling object and the interface interaction process of Target crops is
Interface transmittance process, research shows that due to droplet cannot in target blade face effective wetting, sprawl, adhere to, occur spring, it is broken,
Be lost etc., about 35% transmitting can be caused to lose；Therefore, third process plays especially in the effective transmitting for determining preparation
Important role, this process often determine whether pharmaceutical formulation has excellent performance in field trial drug effect.This process
The various interface interactions of the drop (hereinafter referred to as drop) and controlling object and/or Target crops that are formed including dilution.Drop
It when reaching controlling object and Target crops, is deposited on controlling object and Target crops, drop is first anti-during the deposition process
It controls object and Target crops moistened surface, sprawl, then drop retraction bounces, and a part of drop takes off after bouncing
From controlling object and Target crops, another part is then deposited, and under equal conditions, how much is the drop that this part deposits
Decide the quality of the Field information effect of preparation.When the interface of crop soaks, dynamic surface tension influences drop
The intensity of retraction and spring occurs for drop, and drop retraction and spring influence drop are on controlling object and Target crops surface
Deposition and adherency.The static surface tension of drop then influences the final spreading area of drop.In drop and controlling object and target
Crop is related during acting on the physical and chemical processes such as soak, sprawls, bouncing back, bounce, can use adhesion strength, deposit
Amount, contact angle, dynamic surface tension, static surface tension, apparent free energy etc. carry out overall merit characterization.In wet processes
The surface tension of drop must be less than the apparent free energy of controlling object and Target crops, drop ability wetting and spreading, and static state connects
Feeler is smaller, and wetting and spreading area is bigger；Drop bounces back at once after interface is sprawled, in this process surfactant
Interface is mutually moved to from body, dynamic surface tension is shown as and constantly declines, during drop spreads, dynamic surface tension decline
More fast, the power for generating retraction is smaller, and retraction effect is weaker；After drop retraction, drop energy increases, and bounces, in this mistake
Partial drop is detached from controlling object in journey and Target crops surface, remaining drop are opened in controlling object and Target crops surface spreading
Come, it is final to sprawl state and be characterized with static surface tension and static surface contact angle.This serial procedures is in number
Second even completed in shorter time, therefore, set necessary parameter characterized it is very necessary.
