Potassium permanganate is also very suitable for disinfection, and can be disinfected by spraying the soil with potassium permanganate solution or spraying the soil with ferrous sulfate solution before plant cuttings.

Chlorothalonil disinfection is generally made into 1000 times liquid spray substrate for disinfection.

Cuttings and cuttings treatment.

1) Cuttings treatment.

In order to avoid soaking the spikes in large containers for a long time during large-scale cuttings, a higher concentration of plant growth hormone was used for dipping treatment. Before treatment, the ear strips were dipped in 600 750 times of 75% wettable chlorothalonil powder, and then dipped at a concentration of 500mg?L-1 No. 2 ABT rooting powder or indole butyric acid, after spinning dry, it can be used for cuttings.

It can also be replaced with carbendazim or 25% wettable powder 400 times to disinfect cuttings.
