pesticides

Could your lawn, golf course or pasture make its own weedkiller?

IUPAC Symposium 4A – Natural Products, Tuesday 1:45PM – 3:00PM

Leslie Weston, Charles Sturt University, Wagga Wagga

Leslie Weston has discovered and patented two weedkillers made by plants. Now she’s investigating Patterson’s curse to see what tricks it uses to invade grasslands and repel herbivores. Her vision is to use plants or plant extracts to control plants, as an alternative to synthetic pesticides and herbicides.

Greening agricultural sprays

IUPAC Symposium 1A – Formulation: Efficacy and the Environment

Ingo Fleute-Schlachter, Cognis, Germany

Friendlier pesticides are on the way. Every pesticide contains an active ingredient. But there is more in the can. The formulation may need additives and adjuvants which boost performance: working as emuslifiers, wetters, dispersants, or sticking agents to deliver the pesticide to where it’s needed – the surfaces of leaves for example.

Use your spray smarter: save money and the environment

IUPAC Symposium 4B – Formulation, Efficacy and the Environment

Monday 4:30pm

“Current label-recommended levels of pesticides for spray application technology, pest pressure and crop growth structure are vague, frequently resulting in excessive use of pesticide,” says Heping Zhu from the USDA in Ohio.

Putting the spray where you need it

Paul Miller, Waterborne Environmental, Inc

UK scientist Paul Miller will be presenting his work on modelling and thus minimising spray drift.

His work with field trials, wind tunnels and simulations have shown that boom height and the droplet size distribution from the nozzles are the most important variables influencing drift risk with changes in boom height having a greater effect than changes in wind speed.
