Damages and Control of Rose Thrips
Let me share with you some green plant maintenance experience on the damages and control of rose thrips. Next is a comprehensive introduction.
Damages and Control of Rose Thrips
In rose cultivation, it is inevitable to encounter some diseases and pests. Proper prevention and control of rose thrips are essential to ensure their growth and yield. Below is a brief introduction to the damages and control methods of rose thrips.
I. Characteristics of Rose Thrips Damage
Rose thrips primarily damage rose buds, often hiding inside the rose buds and feeding on the ovary and nectar of the small flowers. When the bud scales open, the thrips move and migrate to the unopened bud scales of other rose buds to cause damage. This results in small red dots on the affected areas, which gradually turn black, resembling black spot disease on roses. However, the black spots caused by thrip damage are raised, while black spot disease lesions are sunken. This pest has multiple generations per year, overlapping in generations, and can cause damage to banana flower buds at any time of the year, forming small black dot-like scars. As the banana flowers expand, the scars also gradually increase, affecting the appearance and quality of the rose products, reducing the product value of roses.
II. Control Methods for Rose Thrips
In production, it is necessary to strengthen fertilizer and water management to promote rapid opening of the rose bud scales and shorten the damage period of this pest.
After the rose buds emerge, a uniform application of pesticides should be sprayed on the leaves, leaf stalks, pseudo-stems, and banana buds to reduce the pest source. When the bud scales begin to open, spray pesticides every 5-7 days until the roses stop blooming. After stopping blooming, combine the control of black spot disease, spray with a special blue bag for roses, and cover the flower spikes, which has a preventive effect on this pest. Pesticides such as 10% efficient灭百可 3000 times liquid, 2.5%功夫 3000 times liquid, or 18% 万青 1500 times liquid can be used for spraying.
For the small flowers with opened bud scales, the pesticide spray should be fine-misted and evenly applied inside and out. It can also be combined with the application of growth regulators such as蕉大宝 and 饱满素 to promote the growth of small flowers and enhance their resistance.
The above introduction to the damages and control of rose thrips hopes to bring you some small help in your life!
