Battling the Bugs of Summer

In the summer months, insects can take their toll on your plants if you are not on the alert for problems. If the right product is used at the right time and under the right conditions, however, pesticides can be reduced to a minimum and your plants will be well-protected.

Organic Products

Apply organic products early in the morning when bugs are eating. To stop insect damage, the spray must be applied to the insect itself or sometimes to where the bug is eating. The entire plant must often be sprayed to keep the pests from moving on to untreated areas. Organic controls include insecticidal soap, Bonide All Season Spray (horticultural oil), Bonide Insecticidal Soap, EcoSmart Organice Garden Soap, or Ortho Rose & Flower Insect Spray.

Contact Products

Inorganic in composition, these insecticides must be applied either to the insect or the leaf where the pest is feeding. Apply in the morning for best results, and as with the organic controls, soak the entire plant so the insects do not find a safer spot to nibble. Contact pesticides include Malathion and Bonide.

Systemic Products

Systemic insecticides circulate to all parts of the plant. Therefore, if you are only able to spray part of a shrub, the product will move to all leaves within 24 hours to control feeding insects for about two weeks. Systemics are best applied in the evenings when there is no chance of rain and sprinklers will not be used. The product will be absorbed only as long as the leaf stays wet. When the leaf dries by mid-morning, the product is then moved through the entire plant when the insects resume feeding. Systemic insecticides available to the homeowner include Bonide Systemic Insect Spray, or Ortho Systemic Insecticide.
