Disease and Pest Control of Golden Bract Flower
The golden bract flower is famous for its golden bracts, but many flower enthusiasts often suffer from withered plants due to diseases and pests. As a typical tropical flower, the prevention and control of diseases and pests need to be combined with its growth habits. This article will systematically analyze five common problems and scientific solutions.
Three Disease Control Guidelines for Golden Bract Flower
Deep Causes of Root Rot
Waterlogging and root rot account for 65% of maintenance problems, and poor soil ventilation plus excessive watering are the main causes. It is recommended to use ceramsite as the base and a peat soil formula, immediately cut off necrotic roots when rot is found, and soak in a solution of 800 times of carbendazim before potting.
Double Causes of Leaf Yellowing
In addition to fertilizer burns, iron deficiency accounts for 42% of cases of leaf yellowing. Supplementing chelated iron fertilizer every month can prevent it, and applying a foliar spray of potassium dihydrogen phosphate 2000 times solution to the yellowed leaves, combined with the application of decomposed goat manure fertilizer at the roots, can achieve better results.
Environmental Control Method for Powdery Mildew
The incidence rate in winter reaches 78%, and maintaining 45%-60% air humidity is crucial. Wipe with 75% alcohol cotton pads at the initial stage of the disease, and alternate spraying with Lunaecen and Nadiwen when severe, once a week for 3 weeks.
Comprehensive Pest Management of Golden Bract Flower
Golden Period for Destroying Whiteflies
The bud formation stage is the key period for prevention and control, hang yellow sticky insect boards to monitor insect density. Use dinotefuran plus organic silicon synergist during the adult outbreak period, focusing on spraying the back of the leaves.
Biological Control of Red Spider Mites
Release California new small mites for biological control, and choose 43% dinotefuran suspension concentrate 3000 times solution for chemical control, paying attention to alternating medication to prevent resistance.
Systematic Solution for Aphid Control
Use a high-pressure water gun to wash in the early stage, combined with sophoraflavone solution. Plant companion plants such as mint and rosemary to repel insects and establish an ecological protective barrier.
By establishing a "prevention-monitoring-control" trinity management system, the incidence of diseases and pests can be reduced by 85%. Regularly conduct plant health check-ups, combined with physical, biological, and chemical control methods, to make the golden bract flower continue to bloom with golden bracts.
