Corteva Agriscience Inatreq Learning Centre

“Spray application flexibility” with John Fraser, Inatreq active Principal Biologist, Corteva Agriscience

Now that you have watched the video, you should have a greater understanding of:

1. How the i-Q4™ formulation actively optimises spray applications.

2. The impact of varying parameters such as nozzle choice, forward speeds and water volumes.

3. What happens when you mix Inatreq™ active with a product which doesn’t spread well when the spray droplet hits the leaf.

Test your knowledge with our five questions. Once you have submitted your information, you will be able to check your answers.

Faster forward speeds

The use of low drift nozzles

Lower water volumes


Both behaved identically
The i-Q4 formulation droplet stuck to the leaf’s surface while the water droplet bounced off
The water droplet was absorbed into the leaf faster than the i-Q4 formulation droplet


Inatreq active delivered a lowered yield than the standard programme
Inatreq active delivered an identical yield to the standard programme
