During the larval damage period, spray liquor with 50% phoxim emulsion or 50% malathion emulsion at 1000 times(72 cell plug trays), or 80% dichlorvos emulsion at 1000 to 1500 times, which has good control effect. This kind of pests live in the soil and feed on newly germinated seeds or plant roots, stems and sprouts, etc.(polystyrene plug plant trays), often causing serious losses to seedlings and flower production. larvae are called wax, and they are underground pests.
(plastic seedling pots wholesale suppliers panama)Bag city category: commonly known as cloth bag insects and skin insects(1 gallon plastic nursery pots).

They slow the leaves or several leaves together, hiding in them and biting the leaves(4 inch plastic pots bulk). Pests with chewing mouthparts that feed on plant leaves.
Noctuids: Control method: manual removal of worm cysts(long life propagation trays): in the early stage of larval damage, the insect population is relatively concentrated, promptly remove the insect leaves, and focus on destruction: in the larval colonization period or the larval early stage, spray 90% trichlorfon or malathion emulsion 1000 times liquid has good control effect(2.5 inch square plastic pots).
