Unfortunately, the use of beneficial insects, whether introduced or naturally occurring, will be less effective in the non-organic plots if synthetic pesticides are being applied frequently. None of the pesticides used in the course is restricted access, but all chemicals must be treated with respect and applied carefully and safely. Always read the instructions on the container's label. Wear the disposable gloves and disposable facemasks provided and dispose of them in the proper receptacle after use. If you come in contact with any of the chemicals, wash the area of contact thoroughly and report this to your lab instructor.
Some chemicals are to be applied as dusts and others are to be applied as sprays.
Follow the procedures outlined below. In most cases the pesticides will be prepared in the dusters and sprayers before you come to lab. Read the label of any dust that you are planning to apply before you get the duster containing the dust. Only apply the dust when the wind is not blowing toward other students. For greatest effectiveness it is best to apply dusts early in the morning when there is no wind and a film of dew is on the plants.
