Basic rules for pest control
Spraying with decoctions or infusions of plants with insecticidal properties should be carried out at the first appearance of the parasite. If the females have already begun to lay eggs, then this kind of treatment will not give the desired result.
Dusting and pollination is carried out in the morning dew or after rain, while spraying is recommended in the evening, in dry and calm weather.
Ready solutions should be used within 3-6 hours after preparation. Long-term storage negatively affects their effectiveness.
