7. Application Methods
- For Diamondback Moth Control: Dilute 2.5% Spinosad SC to a 1000–1500-fold solution and spray during the early larval stage of the pest.
- For Thrips Control: Dilute 2.5% Spinosad SC to a 1000–1500-fold solution and spray at the early stage of pest occurrence, with a focus on spraying young and tender plant tissues.
- For Head Lice Infestation Treatment: Shake well before use. Wet the hair with the lotion, leave it on for 10 minutes, then rinse the hair thoroughly. Use a comb to remove dead lice and nits. If head lice are not completely eliminated, repeat the application after 7 days.
