A garden, even if you call it an organic kind is never free from the infestation of aphids, ants, snails, slugs and other harmful insects that take leaves of plants as food. If you are unable to check these garden enemies, they kill your plants or they leave the plants unproductive. You have to kill the insects and to keep the vegetation natural you have to implement organic pest control.
How are you convinced that your garden already has the pests? You can look of signs that the slugs or aphids had already established residence in the plants. You can see the white spots on the leaves so there are aphids already. Other pests may already have thrived and eaten the leaves as you see irregular-sized holes. Some seedlings or growing young plants have been stripped of their leaves and stems. It is then time to kill the attackers with your organic weed control pesticides.
There are some ways by which you can eliminate the pests organically. However, in severe cases of infestation, purely organic pest control may not be effective and it may necessitate the use of botanical insecticides. It is important to combat the pests early; if you are too late you might be able to save your precious plants.
Making use of plants as organic pest control
You can make use of plants to keep the insects away. The scent of some plants can repel those pests. You can plant mint, lavender and garlic alternately to the main crop to ward off aphids, beetles and moths.
When the use of organic pest control herbs proves futile, you have to go to your second line of defense; the use of natural pesticides that are short-lived and less toxic than the commercial chemical insecticides. These botanical insecticides are derived from plants. Although they are said to contain insecticidal properties, they are less toxic and they have fewer adverse effects. Because they are not truly organic, use them only in too advanced infestation. Some botanical sprays that are recommended for organic gardening include sabadilla, neem oil and rotenone, all derived from plants.
Insects against garden pests
Another way to eliminate garden pests is through other insects. There are insects that attack other pests. In the process, the plants are left unharmed. As an example, ladybugs in your organic garden can be your organic pest control insect. These bugs love to eat aphids and a single ladybug can eat as many as 60 aphids per day. The praying mantis will not destroy your plants but will kill the crickets that eat your plants.
Minerals and fossils as base for pesticides
There are times when you cannot do without chemicals if you want to conserve the existence of your organic garden. There are times when you are compelled to use mineral-based pesticides. These make use of sulfur which is powdered chemical used as pesticides. This may not be toxic to mammals but they have foul egg-rotten odor. Care is necessary in the use of this pesticide because plants can be endangered when the sulfur’s temperature reaches 80 degrees or more.
Another option to ward off weeds is the use of diatomaceous earth. This is also non-toxic insecticide, mined from fossilized silica shells of sea creatures. The lethal solution from this material is effective in killing aphids, grasshoppers, millipedes and slugs. The edges of the small shell particles will cut the bodies of the insects.
The first line of defense against pests is organic pest control. However when infestation reaches advance stage, this may not be enough and you have to resort to other non-toxic insecticides.
