Pests and Diseases
Cucumber Beetles feed on the stems, leaves and fruits of your butternut plants. You usually see them inside the flower. They lay eggs in the soil. The larvae eat the roots of the butternut plants.
Kill Cucumber Beetles with Nimbecidine from Osho Chemicals. Mix 30ml Nimbecidine with 20 litres of water in a knapsack. Spray the plants 15 days after planting. Repeat every 15-20 days.
Melon flies and White flies
Melon flies feed on the stems, leaves, roots and fruit of your butternut plant. White flies suck the sap from the leaves.
White flies also carry Cucumber Mosaic Virus (CMV). CMV attacks the leaves and causes poor growth and badly formed leaves.
Kill Melon Flies and White Flies with Asataf from Osho Chemicals. Mix 20g Asataf with 20 litres of water in a knapsack. Spray when you see melon flies or white flies. Spray again after 10 days if the attack is bad. If not, spray after 21 days.
Powdery Mildew is a fungus that attacks the leaves. Treat Powdery Mildew with Control from Osho Chemicals.
Mix 12g (1 tablespoon) Control with 20 litres of water in a knapsack. Spray your butternut plants every 14 days.
