Rules for Using Chemical Garden Sprays

Sprays

Chemical sprays are of three kinds; insecticides, fungicides and herbicides. All should be treated with great caution for as well as killing insects, fungus diseases and weeds, they can injure human beings and domestic animals, sometimes with fatal consequences. Always use a sprayer with a nozzle which will produce a fine spray pattern with good coverage of the plants.

Always read the instructions on the packet or bottle and follow them. Never mix chemicals together unless the manufacturer’s instructions on the packet or bottle suggest that you should. There are an enormous number of chemical sprays available which are divided into different types according to the way in which they work. Systemic sprays are carried in the sap to all parts of the plant and will therefore affect pests or diseases in any part of the plant. A non-systemic spray is not carried around the plant and kills pests by poisoning the surfaces on which they feed.

rules for chemical sprays in the garden - weed killers Weedkillers are available in three types: selective weedkillers, mostly used for weeds in lawns; contact weedkillers, which kill all parts of the plant with which they come into contact; and residual weedkillers which remain near the surface to kill weed seedlings as they emerge. Weedkillers should not be used near fruit and vegetable plants nor should they be used where plants are growing close together. Remove weeds from such areas by hand. Unlike insecticides and fungicides, herbicides can be applied with a watering-can, but make sure that it is washed well after use. If possible keep a watering-can solely for this purpose.

 

RULES FOR SPRAYING

  1. Always read and follow the manufacturer’s instructions.
  2. Always wash off accidental splashes immediately and always wash your hands after using a spray.
  3. Always keep containers well stoppered, ensure they are correctly labelled, and lock them up.
  4. Always put empty containers in the refuse bin.
  5. Always wash the spray equipment immediately after use, and never use spray equipment for any other purpose.
  6. Never inhale the vapour.
