Farming Advisories
LA NIÑA ADVISORY
Prolonged rainfall during La Niña, can proliferate destructive grain-sucking rice-bugs (liptocorisa) which can be abundant and can attack any time, be vigilant and always inspect your rice fields and ask local agriculturist for advice if there are any. Continuous wet weather condition brought by La Niña, promotes fungal development and can cause damage to stored farm products, reduce the quality, viability and market price of the grains. Thus, it is advised to keep barns and crop storage rooms to be in good, dry, well ventilated condition. During La Niña, choose flood resistant rice varieties which are suitable in your farm or ask the advice and expertise of your local agriculturist.
IN AREAS AFFECTED BY NORTHEAST MONSOON, TAIL-END OF FRONTAL SYSTEM, AND AREAS WITH MODERATE AND SCATTERED RAINS AND THUNDERSTORMS

Be alert and extra careful to those living in low lying areas and near mountain slopes due to possible flooding and landslides; inspect farm houses, barns and light-built structures and make repairs; Clean creeks, canals and ditches; store harvested crops in elevated, well ventilated and covered places. Water impounding is advisable during heavy rains for future use. Construction of fishponds is favorable during the rainy days
FOR WET (IRRIGATED) AND MOIST AREAS

Land and seedbed preparation; planting and transplanting; removal of weeds and cultivation, harvesting of matured crops, use covered vans in delivery of goods in the market; planting of fruit trees to replace the old ones.
FOR DRY (RAINFED) AREAS WITH LIGHT TO MODERATE WINDS

Watering crops during early morning and evening periods will help alleviate stress on crops. Animal housing must be well ventilated; cogon and nipa as roof materials are advisable. Sun drying of newly harvested rice and corn; watering activities or irrigation using pump.
Fishing Advisories

Rough to very rough sea conditions will be experienced the eastern seaboard of southern luzon (northern and eastern coast of Polillo Islands, Camarines Norte, northern and eastern coasts of Camarines Sur and Catanduanes). Fishing boats and other small seacraft are advised not to venture out into the sea while larger sea vessels are alerted against big waves. Meanwhile, moderate to rough sea conditions will be experienced over northern Luzon and eastern section of central Luzon. Elsewhere, will have slight to moderate seas. Be reminded to be very careful in going out fishing specially those using small sea craft. Always bring emergency kit. Be updated for the latest weather update and farm advisories.

DEKAD NO. 02      11 – 20 JANUARY 2021

Philippine Agri-Weather Forecast
The weather systems that will likely affect the whole country are the northeast monsoon (NE), tail-end of frontal system, low pressure areas (LPAs), easterlies, intertropical convergence zone (ITCZ) and localized thunderstorms.

During the early days of the dekad, cloudy skies with scattered rainshowers and thunderstorms will be experienced over Visayas and Mindanao while light rains will occur over Cagayan Valley, Cordillera Administrative Region, Bicol Region, Aurora and Quezon. At the mid of the dekad, cloudiness with scattered rainshowers and thunderstorms will prevail over the eastern sections of northern and central Luzon, MIMAROPA, Bicol Region, Visayas and Mindanao. The rest of Luzon will have partly cloudy to cloudy skies with light rains. At the latter part of the dekad, Palawan, Zamboanga Peninsula, SOCCSKSARGEN and the eastern section of the country will continue to experience cloudy skies with scattered rainshowers and thunderstorms while the rest of Luzon will have cloudiness with light rains. The rest of the country will have partly cloudy to cloudy skies with isolated rainshowers and thunderstorms.

Northeasterly winds are expected to prevail over the whole country. Easterly winds will then blow over Bicol Region and eastern Visayas. At the mid of the dekad, winds coming from east to northeast will be experienced over Palawan, Visayas, and Mindanao while the rest of the Luzon will have northeasterly winds. Palawan and Zamboanga will have winds blowing from northeast to north while Bicol Region and the eastern section of Visayas and Mindanao will have winds blowing from east to southeast. Easterly to northeasterly winds will then blow over the whole archipelago for the rest of the forecast period.

During the early days of the dekad, rough sea conditions are expected over the seaboards of Luzon while moderate to rough sea conditions will be experienced over eastern sections of Visayas and Mindanao. The rest of the archipelago will have slight to moderate seas. At the middle of the dekad, the seaboards of northern Luzon will experience rough sea conditions while slight to moderate seas will prevail over the rest of the country. During the latter part of the forecast period, rough to very rough sea conditions will then be experienced over the western, northern and eastern seaboards of Luzon, and the northern seaboards of eastern Visayas while slight to moderate seas will prevail over the rest of archipelago.

Farm Advisories

  • (Please observe the Memorandum Order on Stringent Social Distancing Measures and Further Guidelines for the Management of Corona Virus Disease 2019 (COVID-19) Situation)


    Farmers are adviced and reminded for some ways to obtain potential crop production is pest management before transplanting, which are the following:
  • For Insects. Follow regular planting period (not too early or late) to avoid pest infestation.
  • For Diseases. Destroy all infected rice stubbles, ratoons, weeds, and others.
  • For Weeds. Thorough land preparation controls most weeds.
  • For Golden Snail. Herd ducks in the field, hand pick snails, repair dikes and control water; put screen wires along water outlets, construct canalets near dikes and alternately drain and flood the field so snails will transfer to canalets where they can be picked easily.
  • For Rodents. Destroy all breeding sites of rodents. Conduct rat control campaign
  • For additional knowledge to attain potential crop production, farmers are encouraged to join government projects. These will enable them to learn and experience science-based crops and cropping system technologies and gain from such projects’ activities as sample advisories like planting dates, early warning for pest and disease infestation, water management strategies for specific areas, and daily weather condition notifications are also available (e.g. ACIAR, SARAI projecs).
