DeCAL 9820 is designed to partially replace the surfactants typically used in crop spray treatments. E.g. tallow amine ethoxylate found in standard glyphosate formulations.
DeCAL 9820 is a drift reduction aid which also gives reduced leaf bounce and enhanced adhesion.
There are four major difficulties in spraying herbicide and pesticide crop treatments, namely drift control, droplet bounce, product absorption through waxy leaves and rain fastness. Low dosages of DeCAL 9820 of 100-400 mg will narrow the droplet size distribution to reduce fines and inhibit drift. Its contribution to surface chemistry and internal rheology results in greater droplet adhesion to the leaves. This can also resist rainfall wash-off.
