Garlic is effective and safe pesticide


Dr Abe V Rotor

There's a universal belief that garlic drives evil spirits away. Well, 
this time it's insect pest that it will drive out of your garden.

Here are five ways to do it, entomologists (experts on insects) tell us.

1. Plant garlic among your garden plants, say mustard, tomato, pepper, okra, beans, and let it grow with them. Here is a caution though. Don't plant it too close to the crop so as to avoid its allelopathic effect (chemical secretion from its roots to compete with nearby plants).

Garlic serves as natural repellant of insects that would otherwise attack these crops, as well as ornamental plants. You can even harvest the bulbs at the end of the season. By the way, fresh garlic leaves are used in the kitchen like those of its relatives, kutchai (Allium tuberosum) and onion (Allium sepa). Try on fried eggs, batchoy and mami.

2. Hang garlic bulb on trellis and viny crops like patola (Luffa), ampalaya, cucumber, sitao, batao, and the like. Garlic exudes a repelling odor that keeps destructive insects at bay. Now and then crush some cloves in the open to refresh the garlic odor.

3. Make a spray solution direct from its cloves. The simple method is to soak crushed garlic cloves in water for a few minutes, then spray or sprinkle the solution on plants attacked by aphids, mites, caterpillars, and other pests. Adjust strength of solution to the severity of infestation.

Other than its repellant properties, garlic is also anti-bacterial and anti-viral. It could be for this that it was used to ward off the Bubonic Plague carrier - a flea (Xenopsylla cheopis) during the Dark Ages in Europe. It's no wonder people at that time believed in the power of this species of the Lily family in driving away evil spirits.

4. This is another method. Soak approximately 100 grams of chopped garlic cloves in about 50 ml of mineral oil (turpentine or kerosene) or cooking oil for 24 hours. This is then slowly mixed with 500 ml of water in which 20 grams of powdered natural soap (Perla or Ivory) has been dissolved. Soap serves as emulsion to make oil and water miscible. Stir the solution well and strain it with an old shirt or nylon stocking, then store the filtrate in an earthen or glass container and keep it in a cool, dark place.

This serves as mother stock, ready for use, diluting it one part to twenty parts of water, or down to one part per hundred. It is reputed to be an effective insecticide against most common garden pests. It can be sprayed or sprinkled liberally on practically all plants, including ornamentals and orchids.

5. Garlic is planted as "trap crop." In spite of its repellant properties garlic is not pest-free. There are insects that attack it, such as thrips (Thrips tabaci), flea beetle (Epitrix), white flies (Bemesia), and some plant bugs (Hemiptera). Just allow the standing garlic plants to attract these insects, thus saving other crops from being attacked by the same insects. Then rouge the infested garlic plants and burn together with the pest.

Garlic can save us a lot of money, and eliminates the hazard to health and environment caused by chemical insecticides. It is an ancient practice in the Fertile Crescent, Egypt and ancient China, a key to natural and sustainable farming and a balance ecosystem.

Let's revive this simple practice today.~
