Full article on thrips
Colleague: The other day, thrips flew onto the balcony. I immediately sprayed the plants on the balcony with confidant in the proportion of 1 gram per half liter of water. By evening, dead thrips fell from the plants. I never saw them again. The confidor had no effect on the plants, they grow as they grew.
Kroky: For ticks and thrips, I successfully used phytoverm spraying, it was enough 1 time, the second for my own calming. A week later, to support the plants - treatment with epin. Bazudin was poured into the pots from mushroom mosquitoes, it also helped. Bacterial contamination of begonia was cured by spraying with a systemic fungicide from Bona Forte once.
1. If thrips appears on a plant, especially a flowering one, be sure to remove ALL flowers and buds, as thrips loves to settle in them.
2. Since thrips has a complex life cycle of development, one of the phases of which it spends in the ground, it is necessary not only to thoroughly spray the plant, but also to shed the soil.
3. It is necessary to carry out at least three treatments, observing the intervals between them 7 days at an ambient temperature of about 20-23 *. At higher temperatures, the thrips development cycle is accelerated and the intervals between treatments should be reduced to 5 days. At temperatures below 18 * poisons become ineffective and processing is not carried out. These intervals must be respected so that newly hatched individuals do not have time to lay eggs, otherwise the fight against thrips will be endless.
4. Concentration of phytoverm for thrips control - 1 ampoule per glass of water. Unused solution cannot be stored.
The larvae of thrips are small, whitish, very mobile "worms" - the scourge of the Gesneriaceae. These pests eat up the anthers of flowers, cause deformation of flowers and buds, not to mention leaves damaged by punctures.
It is very difficult to fight thrips on the Saintpaulias collection. It is usually recommended to pick off all flowers and buds - this is where the larvae of thrips are hiding. And sometimes it is possible to notice them only when severe damage is already visible. By the way, it is noticed that blue flowers are especially attracted to thrips, although during mass reproduction, the color does not matter - they devour everything.
The fight against thrips is complicated by the fact that adult flying individuals easily hide in places inaccessible to insecticide spray, and thrips lays eggs in leaf tissue, and the pupa formed from the larva often falls on the ground, where, due to its immobility, it also remains unnoticed.
Therefore, in the fight against thrips, you need to spray the plants, sparingly remove flowers and buds, and water the ground with a systemic insecticide.
In my opinion, one of the best tools is aktara. Dilute for spraying 4 g of the drug in 5 liters of water. Spray Saintpaulias from a fine spray bottle, and thoroughly moisten the entire surface of the earth - for watering 1 g of the preparation per 10 liters of water. Do not be lazy and make two solutions of different concentrations so as not to harm the plants.
Repeat the treatment after 7 days.
