Disease prevention

Depth of smoking (such as stink bugs, aphids and aphids): Using hands to kill or spray Bi58 0.05-0.1%, Basa 0.2%. Drawing amulet: Spray Padan 95WP with concentration of 0.05-0.1%, or use 20ml Decis 25EC + 1 liter Bi58 mixture and dilute with water concentration of 0.05-0.07% to spray.

White spider causes fruiting : Spraying sulfur powder 20-25kg / ha or Zineb 0.3-0.5%. Red spider: Spray Polytrin 40EC at 0.1%, Supracid 40EC 0.2%. Stem borers, branches: Getting killed to cut the hair, break the branches early, take the cloud to catch the worm.
