Buying Guide

Insecticides, herbicides, and herbicides are often used interchangeably, but they all have slightly different definitions.

  • Insecticides – Insecticides are a combination of chemicals, either organic or inorganic, that are specifically designed to kill insects. They can be general whereby they kill all insects, or system insects that kill specific types of insects.

  • Practice Crop Rotation – Some crops are more susceptible to a type of insects than others. To avoid the spread, plant different crops every season.
  • When it’s possible, use raised garden beds – Raised gardens help you grow vegetables and ornamental crops on controlled yards. Since they are above the ground, you will be protecting your plants from insects and weeds. You can also create small amounts of compost soil, or even purchase some, and use them on the raised beds.
  • Clean the debris on your farm – After weeding, don’t leave the dead plants lying around the farm. As much as they become humus and benefit your plants, they can still facilitate the breeding of insects. You can include them in a compost heap to create manure instead.
