Helpful Information
Mist Spraying Versus Hydraulic or Dilute Spraying
Dilute
or hydraulic spraying patterns (below left) produce large spray droplets
which run off crops, wasting water and chemical. Mist spraying (below
right
will give you better distribution of small spray droplets which produce
better
penetration and coverage while using less chemical, water and time.
