About RCM Health Care

RCM Health Care one of the component tools of the RCM Advisory Service for rice-based farming. It diagnoses through an interview of a farmer the crop health problems during the season and then providing solutions sent to farmers via SMS. It also provides recommendation to better manage the next rice crop.

RCM Health Care is designed for on-line use by extension workers, technicians, crop advisers, and providers of services who interview a farmer using a personal computer, smartphone, or tablet. The interview is conducted anytime from crop establishment until before harvesting the rice crop. Collected information is then transmitted via the Internet to the RCM Health Care ‘model’, which determines and transmits a crop health management guideline within moments back to the computer, smartphone, or tablet. Each guideline provides an actionable and unique recommendation for the crop, which matches the location-specific crop health problem diagnosis. The guideline is provided to the farmer as series of SMS during the season to the mobile phone of the farmer.

The concept and framework for RCM Health Care was developed by IRRI to complement the recommendation from Rice Crop Manager before crop establishment. The following projects and organizations contributed to the formulation and field testing of RCM Health Care:

The development, testing, and refinement of RCM Health Care were made possible through support from the

Recommendation to farmers via SMS during the season:
  • Golden apple snails: Hand-pick snails and crush egg mass in the morning and afternoon. Use attractants such as papaya or cassava leaves. Keep water below 2 cm. Use molluscicide as necessary. Ask local agricultural technician for information and safe use of molluscicide.


  • Golden apple snails. Do not apply molluscicide after 10 days after transplanting. Use of molluscicide should be immediately after transplanting


  • For next cropping season, control snails during land preparation. Apply molluscicide near crop establishment. Ask local agricultural technician for information on molluscicide.


  • If water can be controlled, keep water below 2 cm.


  • Replant missing hills up to 20 days after transplanting with extra seedlings in the field.


  • Move seedlings up to 21 days after sowing into gaps without rice plants.


  • Whorl maggot damage. Do not apply insecticide. Plants can compensate for damage.


  • Brown planthopper (BPH). Monitor BPH weekly up to booting. Cross the field diagonally, grasp 10 to 20 hills and look for BPH at the base of stem. If BPH is 1 per stem or less, do not spray insecticide. It kills natural enemies of BPH. If the BPH is more than 1 per stem, apply insecticide with buprofezin as active ingredient. You may also use entomopathogenic fungi or neem oil if available. Ask your local agricultural technician.


  • Consider using varieties with tolerance to BPH next cropping season. Use Ask your local technician for list of varieties.


  • Green leaf hopper. Monitor nearby fields for discoloration of leaves to yellowish-orange color that is possibly tungro infection. Do not spray insecticide for GLH. It is often unable to control GLH.
