What to Do If Roses Have Worms
Rose Diseases and Pests
Roses are adaptable to a wide range of climates and soils, but are best planted in loose, fertile, organic-rich, slightly acidic, well-drained loamy soil.
If roses are not properly maintained, they can develop diseases and pests, mainly including caterpillars, scale insects, aphids, rose sawfly,spider mites, and borers.
Reasons for Worms on Roses
The pests on roses mainly harm the new shoots, tender leaves, and flower buds in groups during spring and autumn. They can cause the roses to weaken, stop growing, and even fail to bloom. Moreover, they can also lead to sooty mold and viral diseases.
Solutions for Worms on Roses
1. If roses have worms, it is advisable to clear away the dead branches and leaves in winter and burn them in a concentrated manner to eliminate the overwintering adults and reduce the source of pests.
2. When roses enter dormancy in winter, you can spray lime sulfur solution. If the pest infestation is severe, you can spray carbaryl or alcohol solution or imidacloprid to control the pests.
3. When roses start to show signs of pest infestation, you can spray diazinon, imidacloprid wettable powder, emamectin benzoate emulsion, pyrethrin wettable powder, or dimethoate emulsion.
What Pesticide to Use on Roses with Worms
Once roses have worms, immediately spray with trichlorfon crystals or deltamethrin emulsion. During the peak period of larval hatching, spray with buprofezin wettable powder and promptly use imidacloprid wettable powder. For a small number of potted plants, prune the branches and leaves with pest damage as soon as they appear, or use phoxim emulsion for a large number of plants.
Smart Tips for Dealing with Worms on Roses
If roses have worms, you can boil chili peppers in water for about half an hour, and then spray the filtrate on the affected plants. You can also mix laundry detergent with water, stir into a solution, and spray 2-3 times consecutively to control pests. Alternatively, mix laundry detergent, urea, and water in a ratio of 1:4:100, stir, and then spray on the plants, which can both fertilize and kill pests.
Preventive Measures for Rose Diseases and Pests
Roses are highly adaptable to the environment and are best planted in breathable, loose, acidic soil. They need plenty of sunlight during the growing period, and watering should follow the method of "not watering when not dry." There should be no waterlogging in the pots, and good ventilation should be maintained. Timely pruning of faded flowers and withered branches can reduce diseases and pests.
The above provides a comprehensive introduction to dealing with roses infested with worms, hoping to bring some knowledge about green plants to rose enthusiasts.
