Makabuhay (tubli)
An excellent source of insecticide In a research conducted by the Philippine Council for Agriculture, Forestry and Natural resources Research & development (PCARRD) at the U.P Los Baños, it was found out the juice of 50 grams of makabuhay for 1.25 liters water can control rice green leafhoppers, insect
that bring the virus of the disease in palay.
PLANT PESTICIDES FOR RICE PESTS
Certain plants, not harmful to the environment or to the user, repel the black insect pests that
attack rice plants. Some of these are the tubli (or labnek) lagtang(or macasia) and the
makabuhay(derris).
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 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.
