What chemicals to use in a RYOBI Garden Sprayer & when to spray your garden

What chemicals to use: 

• The product is designed for spraying consumer-grade home and garden chemicals, such as insecticides, fungicides, weed-killers, and fertilisers. The product may also be used to water plants.
• Don't use corrosive chemicals.
• Don't use the product for any other purpose.
• To reduce the risk of accidents and damage to the product, never operate with:
  • flammable liquids
  • viscous or sticky liquids
  • caustic or corrosive chemicals
  • liquids hotter than 50°C
• Clean the Sprayer after every use.
• Refer to the instructions on the chemical you are using for any further instructions.

When to spray your garden: 

• Most herbicides work best when applied during several days of dry weather, but not extended dry periods. It should not be too hot or dry, because the heat stress will reduce the weed's capacity to absorb the herbicide.
• Avoid spraying on windy days
