During the rainy season every year, orchids grow fast and are also the times when pests and diseases breed the most. Humid environments and sweltering hot weather create optimal breeding conditions for pests and diseases.
Here we focus on the most annoying pests on orchid leaves: snails and slugs. This mollusk not only nibbles on orchid leaves, but also infects the bite wound with germs. At the same time, they are not like the general pests, which can be difficult to pick up by hand.
Snails lay a lot of eggs at a time, mostly hidden at the base of the leaf or in the leaf sheath. During the day, it is rare to see their footprints, generally late at night to early in the morning, which is the most rampant time for snails and slugs. Lan You often said to me: The orchid that was fine the day before, only overnight, found a dense slug and snail on the leaves, what can I do?
Don't worry, any pest has a drug that specializes in dealing with it, and snails and slugs are no exception. A common medicine for agricultural cultivation is recommended here, and it is very effective in killing slugs and snails. Tetraacetaldehyde is a highly selective snailicide. The appearance of light blue softens with water, has a special fragrance, and has a strong seductive force.
When snails and slugs are attracted by attractants and eat or come into contact with the agent, the body acetylcholinesterase is released in large quantities, destroying the special mucus in the soft body, making the body rapidly dehydrated, nerve paralysis, and secreting mucus, due to the loss of a large number of body fluids and the destruction of cells, resulting in snails, slugs and so on in a short period of time poisoning death.
