Description
Technical field
The present invention relates to applications of pesticide fields, and in particular to a kind of anti-drift composition and its application.
Background technique
General pesticide is administered all after being watered dilution with spraying instrument.Droplet is during the falling process by temperature
The influence of degree, humidity, wind direction, wind speed etc. is easy drift, and especially tiny droplet is easier drift.It is generally acknowledged that 150--400
The drop of micron is that drift minimizes and the best drop size of deposition effect.Easy drift less than 150 microns is greater than 400
Micron drop although resistance to drift but be easy popped up by blade face, deposition effect be deteriorated.The amount reduced less than 150 microns of droplets can be shown
Writing reduces spray drift.At present generally by new nozzle technology or the polymer by the way that macromolecular water-soluble is added as anti-
Drift agent, but these high-molecular compounds are generally more difficult is scattered in water and cannot adhere to well with blade face.
Application number 201710157186.5, a kind of entitled anti-drift composition and its preparation and application, belong to agriculture
Medicine applies field.The anti-drift composition, consists of the following components in percentage by weight：5%~90% metal silicates are compound
Salt, 5%~60% weight gain component, surplus are organosilicon.Although the patent of invention can reduce fine mist specific gravity, increase droplet
Anti-drift performance, but the principle of its anti-drift is by increase droplet weight to reduce droplet drift distance, and organosilicon
The effect for primarily serving wetting and spreading is not obvious the evaporation and pop effect that prevent droplet.

The size of mist droplet particle size characterizes the size of the anti-drift ability of droplet, the in general anti-drift of big droplet to a certain extent
Ability be eager to excel.As shown in Table 1, in terms of detection data, composition of the invention and water and the agriculture for not adding the present composition
Medicine is compared, and the median particle diameter of droplet volume can be significantly increased, and reduces the ratio of fine particle size.
2, droplet drift experiment
Measuring method：It is phonetic that 1.0% solution that above-described embodiment preparation anti-drift composition is made into mass fraction is added to 25%
It is comparison with water and 25% Fluoxastrobin SC in bacterium ester SC dilution, the BSF that concentration is 0.1% is added in spray liquid to be measured and makees
For fluorescent tracer.The operation cell that area is 50*20m is divided, under operation cell at the 20m of air port, placing five height is
The rotation drift collector of 1m, collector are the long stick of plastics for being stained with Teflon film.In lower air port respectively apart from operation area side
Culture dish holding at edge 1m, 3m, 5m, 10m, 15m, 20m, each distance place 5-10 culture dish, controlled wind speed, temperature when test
Degree and humidity are essentially identical, calculate drift potential index DIX by the amount of BSF on measurement culture dish and the long stick of plastics, as a result see
Table 2.
The DIX index of the anti-drift composition of 2 different formulations of table
| Experimental subjects | DIX index |
| Water | 0.58 |
| 25% Fluoxastrobin | 0.57 |

DIX data are smaller, it is meant that a possibility that drift losses is smaller, i.e., anti-drift ability is stronger.As shown in Table 2, of the invention
Anti- drift composition to float of mist droplet have certain inhibiting effect.
3, herbicide synergy effect measurement
Measuring method：By taking 41% glyphosate isopropylamine salt water solution as an example.Citrus is carried out using antidrift agent composition of the invention
Garden weeding experiment.41% glyphosate isopropylamine salt water solution is diluted 200 times when use, water consumption is 30kg per acre.According to 1%
Composition prepared by embodiment 1-10 is respectively added in the medicament after dilution by additive amount, is observed after 7 days miscellaneous in citrus orchard
The control efficiency of grass, test result are as shown in table 3.
The case where anti-drift composition of 3 different formulations of table is to herbicide synergy table
| Experimental subjects | Weeds integrated control effect after 7 days |
| 41% glyphosate isopropylamine salt water solution | 88.3% |
| Example 1 | 96.7% |
