Geranium pests with photos

Pelargonium is said to be an unpretentious plant and its main advantage is that it is “tasteless” for most pests. I thought so too. “Well, I know what the whitefly looks like,” I thought, “if I examine the plants more often, I will see both the whitefly nymphs and adults and I can handle this business with Aktaroy.”
For a long time I was just sure that it is the whitefly that is the most terrible enemy of pelargoniums, not a squeamish such enemy who chews everything. Even tasteless bitter healing geraniums. But it turned out that there are more such “not squeamish” and “omnivorous” ones. Disease or pest?

In the summer, my pelargoniums stood outside, and in the fall I began to bring them into the house. My first mistake was that I did NOT transfer them into a pot with a smaller volume (although I have all the pots small) and did NOT change the soil. As a result, together with the ground, I brought into the house a lot of interesting things: from ants to caterpillars. For example, I took out mushroom mosquitoes for a long time.
Having overcome the same flocks of mosquitoes, I already sighed with relief: the plants were clean, I found a place for everyone. And for those who didn’t find it, she persuaded her husband to make me a shelving with lighting.
Where to take trouble? Now they are safe and can spend the winter quietly. But it was not there.

At first, on many pelargoniums, the lower leaves began to turn yellow and die off. "Bullshit" - I thought - "Autumn, the plants slow down the growth, the natural dying off of the lower leaves. No problems. Soon the very end. " In principle, all, of course, so. And yellowing and dropping of the lower leaves in the fall (and not in the fall) is a normal process. But perhaps this is not just yellowing and dying off. Perhaps this is the beginning of some byaki. However, after examining the leaves from above and not finding a whitefly on them, I calmed down.

And the process went further. The leaves are no longer just yellow. They rather acquired a gray-brown color, were dry. Not only the lower leaves, but also the upper leaves, either dried, grew brown on the edges, fell or hung on dried stems. And only the newly released leaves remained seemingly quite healthy. mite on pelargonium

I climbed into the Internet to read what was happening and how to deal with it.

There are many similar photos on the Internet. People ask "What is with my geranium?", "Help save pelargonium", "How to treat pelargonium?", Etc. In most cases, looking at a similar picture, it is advised to treat the plant with a systemic fungicide. Yes, it looks very similar to some kind of fungal disease. I have processed pelargonium fungicide Alirin-B. I cannot say that it has become much better, but the process of drying the leaves has slowed down a bit. I calmed down again, but not for long. When Alirin-B didn’t help much, I tried to drown out this “fungal attack” with the FitomPorin-M treatment series. The effect was the same.

Ivy pelargoniums especially suffered. I could not save some varieties: even the cuttings removed from the mother plants did not want to take root. But it seems that I finally found the source of the problems. Ticks - the problem is not only fuchsia and roses. Pelargonium mites settle too!

Ticks sucking from plant juices are very small! They can not be seen with the naked eye! These are not spider mites, which entangle a plant with such a spider web that leaves are not visible. These are not red ticks that crawl along the trunk of a plant and you can make a movie about their life and migration. These microscopic mites with a size of 0.2-0.5 mm do not show their presence in any way. But their "work" you will see in all its glory.

Like all mites, (not blood sucking) they prefer dry air and heat. With the beginning of the heating season in our apartments for them a real paradise! Dry, warm, rain does not happen, and the movement of air is minimized.

They, sucking the juices from the leaves, leave behind a picture as after a fungal disease. Dry brown-gray leaf, slowing plant growth and development. When the mites get to the most delicate upper leaves, they turn black, droop, hang on the stems.

Take a healthy-looking leaf from a diseased plant and look through it into the sunlight. If you have seen lighter tiny dots on the leaf, most likely a tick is operating on this plant.

It all starts with yellowish specks, then in this place large discolored and dried-up areas grow, leaves fall, the plant dies. if the tick is not in time to detect and not neutralize, there will be something like this if the tick is not detected and neutralized in time, there will be something like this How to save pelargonium?

Ticks are far from sensitive to all insecticides. For them, the industry has developed a special line: acaricides. These include Bitoxibacillin, Fitoverm, Akarin, Vertimek, Molniya, Fufanon, Kemifos, Karbofos-500, Ditox, Bi-58, Karate Zeon, Kungfu, Antiklesch, Iskra-M, Aktellik, Omayt, Tovit Jet, Zolon, Oberon, Sunmite and others. It is useless to treat the plant from the tick with “ordinary” insecticides!

Attention! Many growers say that ticks die quickly, but you need to be careful with the preparations. Firstly, they can be quite toxic (I, for example, have a terrible headache from Fufanon. Yes, and Fufanon smells, that Actellic is literally on the whole house!), And secondly, ticks quickly get used to the drug, if used wrong.

Health to your plants!
