Treat Your Garden Right With Organic Pesticides

How to get rid of pest in your garden

Which gardener don’t want to get rid of  all those nasty summer pests? Putting chemical pesticides in the plants ultimately grow the products but the food is not healthy. That’s where gardeners started using organic pesticides for use in the garden. These are safe and do not harm the soil anytime.

Many of the organic pesticides are extracted from plant sources. Some of  the plants produce pyrethrum while others produce rotenone, ryania, or mineral-based pesticides. This so called mineral-based pesticides include cryolite, boric acid or diatomaceous earth. These pesticides are all designed to kill plant-destroying insects in your garden.

As we know organic pesticides are clearly safer than synthetic pesticides, but one must be careful in using them. These organic pesticides should not be used with bare hands. You should realize that some organic pesticides can be as toxic as their non-organic counterparts. While buying from the store see its label. Less toxic products are usually labelled “Caution” while the more toxic products are either labelled as “Warning” or “Danger”. However, these labels are nothing to do with the environmental damage.

Some of the organic pesticides are less toxic to humans, but are very toxic to animals. while some of them even kill the most beneficial insects, for example, the combination of pyrethrins and rotenone.

Different types of Biopesticides

An important group of “organic” pesticides is the group of biopesticides. This unique class of pesticides involves the use of biological organisms to control pests. In general, this type of organic pesticide acts more slowly than other organic pesticides. Biopesticides reduce, rather than destroy, pest populations and have a limited target range with a specific mode of action. They have a limited shelf life, as they are living organisms.

Organic biopesticides has two types – biochemical pesticides and microbial biopesticides.

  • Biochemical pesticides include insect pheromones, odor-based chemicals that disrupt the insect’s mating cycle. They interfere with the ability to find a mate. Pheromone traps are used to trap male insects thereby disrupting the mating cycle.
  • Organic microbial biopesticides are derived from fungi, viruses, protozoa or genetically modified bacteria. This type of organic pesticide suppresses the pest population by secreting insect-specific toxins. This also cause diseases to the pest population. This will help interfere with pest establishment through competition and other modes of action.

One of the organic biopesticide is the bacterium known as Bacillus thuringiensis. This is a soil-based bacterium that is toxic to various types of insect larvae, but not to other things. This bacteria can be applied to the foliage of plants or incorporated into the genetic material of larger crops. It is toxic to larvae of moths and butterflies. However other varieties of bacteria are toxic to mosquitoes and black flies.

Gardening with organic pesticides is generally effective and healthy for the environment and plants. At the same time synthetic pesticides will make your garden harmful.
