City of San Fernando, La Union - Do you know that the guapple farms in Bauang, La Union is being bugged by several production problems?  Mari Cor Ramos, President of the Guapple Farmers  Association of Bauang, together with other guapple farmers revealed that they are having a hard time in controlling the insect pests and diseases infesting several guapple farms in Urayong and nearby barangays.
“White grubs or abal-abal almost completely devastated my farm”, lamented Mr. Amado Pulanco of Urayong, Bauang.  White grubs attack the guapples by eating the tips of the roots causing wilting and eventual death in heavily infested plants.  White grubs or June bettle is destructive during the 7-months larval stage living underneath the soil.

The Department of Science and Technology Region 1 (DOST 1), introduced appropriate technologies in a bid to help the Bauang guapple industry and the farmers thru the Consultancy for Agricultural Productivity Enhancement (CAPE) program.  Director Elsa Chan said thru the CAPE a team of entomologist, plant pathologist and crop production specialist were deployed to the guapple areas to validate the claims of the farmers and identify appropriate interventions.

The experts identified the other insects pests such as stem borer, fruitflies, leaf folder, aphids, mealy bug, white flies, and fruit piercing moth.

The experts also found that the guapples are also infected with fungus particularly attacking the fruits causing rotting in ripening and immature fruits.  Leaves infected with fungus have rusty spots or black areas. 

A Training on Pest, Disease and Fertilizer Management for Guapples was conducted on Nov 5 & 25 2010 for 22 guapple farmers in Urayong and DOST 1, respectively.  The participants were taught the life cycle of the insects, when they are harmful, and the appropriate prevention and control practices like, insect trap or baiting, proper application of clorpyrifos to control borer and  abal-abal and detergent sprays to control mealy bug, aphids and white flies.  Appropriate pesticide use was also presnted to avoid build-up of resistant insect population.

On the other hand, fungal diseases can be controlled thru clean practices like burning of infected fruits and leaves.  The kind of bagging material is presently being tested to come out with better bagging practice which could reduce fruit rotting.

Fertilization management was also taught to the farmers to improve the guapple stand and productivity.

The appropriate technologies are expected to improve the incoming harvests and income of the guapple farmers in La Union.

CAPE is funded by the Technology Application and Promotion Institute (TAPI) of DOST.
