kegiatan tanam semangka part 9 mengatasi njebuk dan keriting pokok

Steps to take when the tree shows signs of "njebuk" (blight) 1. Stop fertilizing. 2. Don't spray excessively with insecticides. 3. Don't under-water. 4. Spray with calcium amino acid. 5. Spray regularly with zot and systemic fungicide. Monitor the tree's progress for 3 to 1 week. If it doesn't improve, apply an abamectin insecticide compress at night every 3 days. Hopefully this helps. #njebuksemangka #keritingsemangka
