- After the incubation process, mix it with water, then spray all within 1 day. To prevent spoiling it must all be done in one day and cannot be kept for later use
- Incubated Bs can be mixed with sawdust while adding water to help make growing materials damp enough to form packs. This will prevent the infection and reduce spoiled packs. (Proportion: incubated juice of a coconut: 100 kilograms of sawdust with dampness level at 60-70%. Mix them well).
- If there is infection in front of the packs, spray there. If the infection is inside the pack, use hypodermic syringe to inject 5-10 cc of incubated Bs into the infected area. If the infection is severe, pour incubated Bs into the packs, let it soak for a while and then pour it all out. Do not leave any Bs in the pack, otherwise the fibers will suffocate.
- If using the soaking technique, give the packs a break to dry and then inject Bt to stimulate blooms.
- If responding to a large outbreak, you can mix 3-4 Chinese soup spoons of Bs powder with 10 liters of water and stir well. It is then ready to be sprayed, but this isn’t as effective as the incubation process.
- Bs powder can be kept for 1.5 to 2 years in a dry place, stored at room temperature (not in the fridge), away from the sun and humidity.
