Summary: Spraying effectively and safety does not happen by accident. These 7 spraying “DO’s” will help keep both you, the plants and the environment safer.
Read chemical manufacturer’s directions and pesticide labels carefully and follow all instructions to the letter when mixing insecticides or fungicides. Strong solutions may do harm; weak ones are ineffective.
Wear a spray mask or respirator, keep shirt sleeves rolled down and use rubber gloves while handling harmful dust or spray materials. Follow manufacturer’s directions and advice. Wear spray suits and other PPE equipment even when spraying with garden sprayers. Homeowners only need good hand held sprayer like this one from Solo.
Choose a day when air is still so spray material will not be needlessly wasted.
Be careful in using weed killers lest the spray reaches nearby plants. Concentrate on the plants to be killed, aiming the spray away from useful ornamental plants growing nearby.
Make certain that material used in dusting or spraying is spread on tops and undersides of leaves. Remember contact sprays for sucking insects must touch insects in order to kill them.
Reserve special spray equipment like a weed killer sprayer or for other materials which leave a residue in the container that would be harmful to other plants. Also select sprayer container size to fit the job.
Wash aphids off plants with water by applying a strong stream of water from a garden hose. Poisonous sprays and dusts may kill goldfish and harm birds which drink or bathe in pool.
