How to mix orchid medication? Try a disposable syringe

Orchidshave entered countless homes; people keep dozens of pots at most, or just a few pots at least. Many orchid enthusiasts thinkorchidsare easy to grow, but when treating pests, mixing the liquid medication is not easy to get right: too high a concentration causes chemical damage, too low a concentration cannot kill the pests. The author uses a disposable syringe to mix a small amount of pesticide (liquid) with very good results (disposable syringes now come in 1ml, 2.5ml and 5ml sizes; which specification to use depends on how much you need to mix. For example, to mix a 1:5000 solution of fenvalerate (sumicidin). A 500ml household sprayer (500ml + 5000 = 0.1ml). Use a 1ml syringe to draw 0.1ml and add it to the 500ml sprayer (this method can also be used to mix Jialanbao, Aiduoshou, rooting promoters, etc.).
