BIO-CONTROL OF CROP DISEASES
Many of our local plants contain helpful chemicals, particularly alkaloids, that are effective against fungal and bacterial diseases of other plants. Thus, they are mixed with the soil to control the fungus that causes the diseases of seedlings. Allow the leaves to decompose for about one week before transplanting the seedlings. Some of these leaves are as follows:
Atis is cultivated throughout the Philippines and is occasionally spontaneous. It was introduced from tropical America by the Spaniards at an early date and is now pantropic in cultivation.
The plant is a small tree to 3 to 5 meters in height. The leaves are somewhat hairy when young, oblong and 8 to 15 centimeters in length, with a petiole 1 to 1.5 cm long. The flowers occur singly in the axils of the leaves and are about 2.5 cm. long. They are pendulous, hairy , three angeld, and greenish-white or yellowish. The fruit is large, somewhat heart-shaped, and 6 to 9 cm in length. The outside of the fruit is marked by polygonal tubercles. When the fruit is ripe, it is a light yellowish green. The flesh is white, sweet, soft and juicy and has a mild, very agreeable flavor.
Cultivation is not very extensive, though the seedling requires constant ring weeding while young..
Farmers in Batangas, Cavite, and Laguna regularly grow filed crops like rice, corn, pineapple, and root crops between young caimito trees to maximize use of land. Other farmers plant fruit trees like banana, coffe and lanz0ones between caimito trees to sterilize all available space.
Fertilizer application is not always necessary. A caimit tree can draw sufficient food from the soil to support growth and fruit production. However, it is a good practice to apply nitrogenous fertilizer when the plants are young. Usually, animal manure is good substitute for commercial fertilizer. To improve fruit production, apply complete fertilizer may also be applied at the start of the rainy season before flowering and when the soil contains enough moisture. The broadcast method of fertilizer application is economical and effective.
Caimito is a medium-sized and spreading tree. Its leaves are oval, with pointed tips, and are light to dark-green on the upper surface, and copper or golden beneath,
Caimito: a tough productive fruit tree
By: Dell H. Grecia and Pit La. Cantilang
Nobody can say with any degree of certainty why it is called star apple or caimito. There have been several wild attempts to explain these names. One corny version has it that the fruit was named caimito because it was first owned and propagated by Mito; thus kay mito
However it got its name, the introduction of this fruit in the Philippines was certainly one of the bsest things to happen to our fruit industry. For star apple or caimito (Chrysiophyllum caimito, L) is now one of the widely appreciated Philippine fruits.
The tree was introduce here in 1905 form the West Indies and Central America. Grown all over the Philippines today, caimito trees are thriving in La Union, Tarlac, Batangas, Bataan, Pampanga, Bulcan, Cavite and many other provinces in the Visayas and Mindanao.
