KALINGAG – insect pest repellant

KALINGAG – insect pest repellant

 

The most damaging insect pest that preys on fruits is the fruitfly. Once it gets into the flesh of

any fruit, it can reproduce and spread wherever that fruit may be brought. Thus, in efforts of

importing countries to avoid the entrance of this pest into their territories, strict regulation are

imposed on incoming fruits, for instance our mango.

 

It was found out by a scientist from the Bureau of Plant Industry in Quezon that the bark of the

Kalingag attracts insects, especially the fruitfly, thus facilitate their entrapment.

 

Procedure:

1. Pulverized the bark of the bark of the Kalingag tree.

2. Mix the powder in 2% water solution that is, 2 grams per liter of water.

3. Put this in containers with traps.

 

The friutflies will approach it, especially early in the morning and late afternoons.

MARIGOLD

MARIGOLD

 

Marigold or amarillo contains a chemical that is toxic to some pests in the soil, like nematodes.

Thus, it is good plant marigold together with vegetable or in between farm crops. Nematodes

are very tiny parasites or worm in the soil, river, sea, rotting wood or plants. They also thrive in

other parts of the plant like the roots, and in animals and insects.

Most nematodes are not harmful but even helpful in the fertilizing the soil however, their

danger lies in that they feed on roots, stems or leaves of plants they suck the nutrient.

PYRETHRUM FLOWER

PYRETHRUM FLOWER Is a kind if white chrysanthemum that grows in high altitudes like the Mountain province. It contains pyrethrin, a chemical that drives insect away. The higher the altitude, the stronger is its pyrethrin content.

 

The pyrethrin or pesticide content in this flower is not harmful to humans and is beneficial to

plants like potatoes. It also repels insects’ pests that feed on cultured plants. Pyrethrin comes from chrysanthemum leaves.

Biological pesticides

Biological pesticides

 

The use of commercial pesticides kills; not only the target insect pests, but also beneficial

insects like spider, grasshoppers and others. Besides this, it leaves residues in the plant

where it is sprayed, and is harmful to the person spraying. If inhaled, pesticide can cause

cancer in the long run.

 

Pesticides chemically prepared are expensive; we have plants that naturally repel harmful

insect at no cost, such as:

 

1. Wild pepper – dried and pulverized

– Spray on infected plants. When this becomes moist from dew, insect pests are repelled.

 

2. Combination of 3 pieces of garlic, 2 pieces pepper, and 2 piece onions grind and pulverize

these, soak overnight in water. By next morning, fill up the water to make 3 gallons. Strain and

spray on affected plants.
