Disinfection of Orchid Seedlings Before Planting

Carry forward the national orchid culture and spread the knowledge of orchids

Disinfecting seedlings is a key measure to put an end to the source of diseases and insect pests, and there must be no ambiguity and fluke mentality. Even if there is no plaque or virus spot in front of your eyes, the latent bacterial and viral diseases are by no means detectable to the naked eye. Therefore, whether it is their own pot-changing seedlings, or foreign orchid seedlings and downhill orchid seedlings, there should be no doubt about pre-planting disinfection.

If shell insects are found in the seedlings, in addition to scraping off the eggs with bamboo or plastic sheets, they should also be sprayed with pesticides or insecticides that can kill eggs. For wild orchid seedlings collected in the mountains and virus-free orchid seedlings, it is not necessary to soak and disinfect them with antiviral agents before planting.

For imported seedlings, whether they are purchased in person from the place of origin, or bought from orchid vendors, or by mail order, highly efficient and broad-spectrum fungicides and antiviral agents should be selected and diluted respectively, and then mixed and soaked for 30 minutes for 60 minutes to disinfect.

Common and effective broad-spectrum fungicides, including those made in the United States that can be killed (fungi, bacteria) and 64% carbametone. The most effective antiviral agent is Virobik. Both fungicides and antiviral agents can be diluted to 300 times and then mixed, and then sufficient water is added, and then 250 times of human edible rice vinegar is added to obtain its extremely strong permeation function and guide the agents directly to germs and viruses. enhance the effect of killing and inhibition.

Drug dilution concentration calculation example: 1 gram of effective medicine plus 500g of water, that is, 500g liquid, that is, 0.2% concentration or 2000ppm. However, because the effective content of various disinfectants is different, their specific dosage has to be calculated. For example, there are only 0.15 grams of active ingredient in the medicament with 15% pouring content.

So if you want to have 1 gram of actual effective medicine, you need to have 6.7 grams of the agent with a content of 15%. After the medicament dosage is calculated, the required water consumption can be calculated according to the concentration requirements, and then the appropriate amount of medicine and water can be prepared into a solution.
