Malaysian Palm Oil Board (MPOB)
Aerial spraying with a Bacillus thuringiensis (Bt) product in Estate A resulted in 50% reduction of the Pteroma pendula population by 30 days after treatment (DAT). In Estate B, the bagworm population was completely under control whilst at Estate C, bagworm larval instars decreased by 90% from 0 to 30 DAT. The Bt aerial spray […]
Sulphur (S) has received limited attention by researchers, agronomists and planters involved in oil palm cultivation, despite the fact that the requirement at tissue level – as indicated by published critical concentrations in Frond #17 – is the same for S and magnesium (Mg) (0.2%). The continuous trend toward S-free fertilisers (urea, rock phosphate, KCl, […]
In view of it’s high water solubility and rapid nutrient availability, kieserite is often used for correcting magnesium (Mg) deficiency in oil palm. However, the same characteristics makes it prone to higher losses in sites with sandy soils, hilly topography or high rainfall. Under such conditions, a less water soluble but equally effective Mg fertiliser […]
