Pests- Thrips

Identification: Thrips are tiny, slender, yellowish to blackish insects with fringed wings. They are typically found on leaves and between flower petals. The adults are very difficult to see without a magnifying lens.

Damage: Both adults and nymphs (immature stage) feed by scraping surface cells to suck plant sap. Leaves fed by thrips will often take on a silvery or speckled appearance. As thrips are very tiny they are not visible to the naked eye. For this reason, it’s very important to monitor the plant closely - if there are silvery spots on leaves, it is probably a thrips damage and it can be managed when detected at an early stage.

Control:
Mechanical- In the early stages, take off damaged leaves with silvery spots to avoid nymphs growing up and making a whole new colony.

Neem oil - It inhibits insect nutrition and fertility, therefore life cycle will be disturbed. Follow package instructions for diluting the oil in water and spray the affected areas, repeat if necessary. Although neem oil is of natural origin, wait a few days after spraying before eating your plants.

Discarding the plants- With a heavy infestation, it may be necessary to discard the plant, disinfecting the garden. Wait for 1-2 weeks before plugging new soils in to avoid continuing pests life cycle.

These are my oregano plants. Some shoots look healthy most have what looks like a fungus/mound. Leaves and at roots.

Should I pull them out. How can I prevent this.

Dear @Claireylou42,

it seems that the main issue here is thrips, not mold. The infestation is quite heavy, please consider the recommendations above given by @Maret

Greetings !
My busy lizzie have been great till a while ago - also buds have been coming. Though the bud are not blooming - before blooming into a flower they are falling off. Also there are some white insects / fungus seen on the leaves. - not sure if they are insects of fungii.

Please check the pictures and help - how to fix it?

Dear @Manisha, good to hear from you!

My first impression is that your plants are infested by thrips, at least the damage seen on the leaves suggests so. If you get a better picture of the pest itself, we can be sure. Thrips start their life cycle inside the leaf tissue and they are quite tiny, so it might be difficult to spot them at first.

Thanks Mia for the reply.

Here are some more photographs with the pest -
Do let us know what best we can do to save the plant and to for buds to blossom…

Dear Manisha,

Unfortunately, the damage visible on the pictures indicates an infestation of thrips. They start their life cycle inside the leaf tissue and the actual pest becomes more noticeable as it progresses.

Please find the instructions in the thread above. To be sure, it is probably best to discard the plants and clean the garden carefully. Also, inspect other plants growing nearby to avoid new infestation.

Thanks for your info. Can you please let me know how the plant could have infected - as the there are no near by plants ? What could possibly be the cause?
So what precautions may be taken for not having such an infestation again with Click And Grow plant pods?
Best Regards
Manisha

Hi @Manisha,

Unfortunately yes, even indoor gardens are not safe from pests. Thrips may just fly in through an open window, or can be brought in with fresh produce or cut flowers.

To be sure, it is the safest to discard all the plants (as the plants are heavily infested) and thoroughly clean the garden. And if possible, take a little break in growing before starting growing again. It is not recommended to use insecticides indoors, as it may be harmful to your health. But next time you may try to remove affected leaves asap and try to treat it with neem oil solutions to prevent heavy infestation.
