What are the symptoms of rose thrips?
Rose infested with thrips can cause significant harm to the entire plant. The leaves will become thinner and thinner due to thrip damage, eventually wilting and falling off. The young fruit will become leathery and feel rough to the touch, affecting both yield and quality. Thrips infestations can occur throughout the year and can be controlled with conventional insecticides such as pymetrozine and acetamiprid.
After being attacked by thrips, the tender leaves become increasingly thin, showing grayish-white or grayish-brown streaks on both sides of the leaf midrib. The leaf surface turns grayish-brown and becomes curled and deformed, eventually wilting. The leaves develop various spots and holes and eventually fall off the mother plant.
When the young fruit is damaged by thrips, the oil glands rupture, gradually losing water and shrinking, resulting in hard and leathery fruit with a corky white or grayish-white spot. It feels rough to the touch, severely affecting the yield and quality of the fruit.
Thrips infestations can occur throughout the year. Thrips are small flying insects that can be black, brown, or yellow. The peak periods are from March to May and November to December each year. Especially in warm and dry conditions, thrips reproduce more quickly. A humidity level of 100% or temperatures above 31°C can reduce the chances of thrips invasion.
If thrips are found surviving on the plant, use conventional insecticides such as pymetrozine and acetamiprid for extermination. After diluting the insecticide, spray it on the roses in the afternoon. If possible, choose systemic insecticides or add organic silicon surfactants, and preferably choose long-lasting insecticides for better pest control.
The above shares the complete content of the symptoms of rose thrips. I hope it can help you and also encourage everyone to check out more green plant and flower cultivation tips!
