Herbicides and Insecticides: What, When, Why, and the Alternatives

Herbicides and Insecticides: What, When, Why, and the Alternatives

by Carrie Stark

When you spend hours on your hands and knees toiling in the dirt to produce crop, you don’t want the aggravation of watching your plants wilt away or be eaten by other creatures. There are various methods to deal with both problems. The most popular method is to treat soil or plants with herbicides and insecticides. The key to solving any problem is to research possible solutions and to determine the best one.

What are Herbicides and Insecticides?

One common solution is to purchase an herbicides and insecticides from the local grocery store. Herbicides and insecticides are part of a larger group called pesticides. According to the Washington State Department of Agriculture a pesticide is a substance that is used to “prevent, destroy, control, repel or mitigate any insect, rodent, snail, slug, fungus, [and] weed.” Some pesticides are specifically designed to eliminate a certain species.

Herbicide is a pesticide that is designed to target weeds that are growing in your yard or garden.

Insecticides are pesticides that are designed to kill, suppress or stupefy insects. They are meant to prevent the insects from eating or destroying plants.

How to Build a Raised Bed Box (alternate method)

This article will describe an alternate method to building a standard Citizen Gardener raised bed box.  The advantage to this method over the standard design is that it uses slightly less wood, wastes less wood, and is slightly simplified.  The disadvantage is the inside diameter of the box is a little less than a full 4′ across, so you can’t get a full 4 ‘squares’ across.

The reason we used this method for one of the classes was that we used cedar wood instead of standard white wood, and couldn’t get the cedar in the 10′ sizes we needed.  It worked out fine, so I wanted to provide this write-up so everyone can see another possible way to build boxes when making their raised beds for backyard vegetable gardening.

Materials (rough-cut cedar lumber)

  • QTY 2: 2 x 8 – 8′  (2 x 10 – 8′ would be more preferable because it gives more soil depth)
  • QTY 1: 2 x 3 – 8′ (2 x 2 – 8′ is also OK)
  • QTY 28: 3″ deck screws (1 lb box is enough)
  • Outdoor wood glue (waterproof)

Cut Lumber

  • Cut both of the 2×8-8′ in half so you have 4 48″ pieces
  • Cut out 4 7″ pieces out of the 2×3-8 (cut to 9″ if using 2 x 10 lumber)
Mark the location near one edge of each board where the 2×3 will be attached.  This should be at 1-3/4″ if using rough-cut lumber or at 1-1/2″ if using standard lumber.  (but measure the thickness of your lumber to make sure)
measure and mark location of 2x3

Measure and Mark the Location of the 2×3 Near an Edge of the Board
