He added that the warm conditions, unfortunately, allow pests, such as spider mites, broad mites and aphids, to breed. These pests attack crops, stunt their growth for weeks and delay harvest.
“There are certain pests which are more prevalent in hot temperatures,” said Mr Ang.
“It’s also difficult because if we ever need to treat the plant, even if we’re just spraying water to try and dislodge the pest, the water and heat don’t go well together. Then you start to run into issues with high humidity and warm temperatures and you get fungal diseases, bacterial diseases.”
