Thrips are a super tiny insect that overwinters in the soil. I don't know if you have them in India or not but these insects crawl up the stem of different plants, especially roses and crawl inside the buds of plants and feed on the immature petals of the bud. Contact insecticides will not work on them. The only way to control them is with a systemic. Many gardeners here use a garlic spray which when applied early acts as a systemic as it will penetrate the the plants outer layer and become infused, thus acting as a poison to many sucking insects such as thrips. Google them. There is a lot of info.@Chuck
What is thrips ? And is it really the cause ?
@marlingardener
Didn't you notice the black(burnt-like) tip of the bud ??
That looks abnormal to me....
Take that damaged bud off and tear it open over a sheet of white paper. If you have thrips they will look like little motes of dust, much smaller than fine ground black pepper. You may not have them but that damaged bud sure looks like what they do.@Chuck
I will try to identify and control thrips on my rose plant.
Hopefully, expecting better results this time.
There was a lot more than one. They will be deeply embedded completely throughout the bud. They are sucking insects a lot like aphids and will become attached to the petals. You will need a magnifying glass to really see themYes....I did that and surprisingly found only one tiny little thing which was maybe white or yellow in color.
It was extremely difficult to be identified by naked eye.
I don't know what was it.....but cant believe....there was only one.
