example 1

[0102] Example 1: Spray Droplet Size Test for Spray Drift Inhibitors

[0103] Thirteen mixtures containing the agrochemical active glyphosate (450 g / l) and a control of water only were sprayed through three different nozzle types (AIXR11002, TT11002, XR11002) at a selected spray pressure of 300 kPA. In the following examples, when referring to a formulation of the invention, it is meant a formulation comprising a spray-drift formulation having:

[0104] · Non-ionic PAM (<150 micron particle size) – 10wt%

[0105] Release agent – ​​2wt%

[0106] ·Polyethylene glycol 6000–10wt%

[0107] Citric acid – 28wt%

[0108] ·Sodium bicarbonate 50wt%

[0109] The measured values ​​are summarized in Table 1:

[0112]

[0113] With Akzel-R-ate TM These mixtures are prepared by adding the measured product mass and calculating the PAM concentration by taking the measured concentrate density into account. There...

Abstract

A liquid spray additive composition comprising: 5 to 15 wt% of spray drift retardant having particle size of less than 150 micron, and an effervescent couple comprising 15 to 30 wt % acid, and 30 to 50 wt % alkali, wherein the composition is in the form of a tablet.

Description

field of invention [0001] This invention relates to the field of spray drift suppression when a liquid is applied as a spray to a locus. In particular, the present invention relates to suppressing spray drift in applications requiring spray application of actives, such as an agricultural, horticultural, pharmaceutical, cosmetic or veterinary active. [0002] In one form, the invention is directed to a composition for dispensing a spray drift inhibitor. [0003] In a particular aspect, the invention is suitable for use in the formulation of spray liquids. [0004] Although the invention will be described with particular reference to spray drift control for agricultural or horticultural formulations, it should be understood that the invention is not limited thereto and may be used in other applications including industrial and medical / veterinary applications. [0005] Furthermore, although the invention will be described with specific reference to viscoelastic polyacrylamide (...
