Gardening Lecture Episode 14: Is this symptom on rose leaves damage from rose thrips? Let's take a look at what leaves damaged by rose thrips look like!

This is the knowledge of Gardening Lecture Episode 14. Today I'll talk about a pest of roses. Thrips, thrips are a pest of roses, but because they are very small, they are relatively hard to spot. But although thrips are small, the damage they cause is great. So what do leaves damaged by thrips look like? Let's step into the Gardening Lecture and talk about it!

Q: How do thrips damage rose leaves?

A: After thrips suck the sap from the leaves, it causes the rose leaves to become poisoned, as it were. At first it isn't obvious, but as the leaves slowly grow you'll notice. The leaves curl + thicken, which leads to low photosynthesis efficiency and affects the growth of the rose.

Q: After thrips damage, what are the symptoms on the leaves?

A:

Curling

Thickening

Deformation

A: Since thrips cause such great damage, what pesticide is better to use?

A: Prevention of rose thrips can be divided into 2 types. Let's take a look.

(1) Physical prevention

Use sticky insect boards, eliminating them by luring them in. Currently this is also the safest method. If you like, you can go buy some sticky boards and put them beside the roses.

More simply, you can make one with a big roll of clear tape, then spray some white sugar on it. The effect is quite good.

(2) Pesticide insect killing

Common pesticides, acetamiprid, imidacloprid, etc., diluted 1000 times and sprayed, once every 5 days is enough. If it is a no-dilution pesticide, it can be sprayed once every 2 days. If it is a standard pesticide, 5-7 days once is recommended.

Q: After spraying leaves damaged by thrips, how should they be handled?

A: Leaves damaged by thrips have basically lost their photosynthesis. We can trim them with scissors, then use a good root-promoting and repair fertilizer to get the rose to sprout quickly. This way we can recover the loss to the greatest extent.

Dilute 500 times and spray. Why use a recovery nutrient solution? Because leaves damaged by thrips have poor absorption capacity. If the rose is not made to grow new leaves quickly, this damage may last a very long time. For later management, I suggest using a good fertilizer to condition it.

Q: After autumn begins, how should roses damaged by thrips be managed?

A: If you want such roses to bloom again in autumn, you have to put in the effort with management. As said before, use a good nutrient solution to condition them. Next, we also need to choose good soil, so that combined with the nutrient solution it can achieve a good effect.

Promoting roots makes the rose's root system well developed. When it absorbs more nutrients, it naturally grows faster. Now is the best time to get into roses. If you have a small balcony, I would not hesitate to choose a Jus fruit, this variety blooms a lot and is a short shrub, very suitable for growing on a balcony.
