II. Calendula Pest and Disease Control
1. Aphids
As one of the main pests of flowering plants, aphids also attack calendula. It is understood that aphids mainly appear in large numbers in spring, sucking the branches and leaves of calendula; they also appear in autumn, harming the buds and petals of calendula. Damage symptoms: calendula leaves turn yellow and deformed, flower buds are ruined, and the flowering period is shortened.
Control method: After discovering aphids, at home you can wipe them off with clean water or soapy water, which works well. When the infestation is severe, spray 1000-2000x omethoate solution, or kill them with tobacco leaf water: add 50 grams of tobacco leaves to 5 kilograms of water and boil.
2. Red spider mites
Red spider mites mostly occur in the hot summer season and are one of the main pests of calendula. They mainly appear on the underside of leaves, piercing and sucking the branches and leaves. Damage symptoms: calendula leaves dry out and turn yellow; during the flowering period they harm the petals, causing the flowers to wither.
Control method: When red spider mites are found, the whole calendula plant should be thoroughly washed with plenty of water, then spray 80% dichlorvos 1000x solution, or 40% dicofol 1000-1500x solution, both of which have significant effects.
3. Spilosoma oblique
One of the pests and diseases of calendula, it rarely appears in home cultivation. It mainly uses its larvae to chew the leaf flesh, causing damage in scattered spots and eating away at the leaves. Damage symptoms: leaves become incomplete with holes, leaving the calendula unrecognizable.
Control method: Spilosoma oblique has low density and weak pesticide resistance. When there are few, they can be removed manually. When there are many, spray a mixture of Guoguang Yike 1500x solution + Leke 2000x; it can be used 1-2 times consecutively with an interval of 7-10 days, with good results.
4. Powdery mildew
Powdery mildew is one of the main diseases of calendula. After it occurs the leaves look disgusting, seriously affecting its ornamental value. Disease symptoms: white round lesions appear on both the front and back of the leaves, and the leaf surface looks as if it is covered with a layer of white powder; the stem is likewise covered with white powder. In severe cases the whole plant withers and dies.
Control method: After the flowers fall, promptly remove fallen leaves and spent flowers to reduce the source of disease. When the disease is severe, spray thiophanate-methyl 1500x solution or diniconazole wettable powder, once every 10-15 days; 2-3 times in a row will show results.
5. Mosaic disease
One of the pests and diseases of calendula, it mainly harms the leaves. Disease symptoms: calendula leaves form a mottled or mosaic pattern, the leaves turn yellow, the plant's growth is stunted and it becomes dwarfed, and the flowers grow deformed.
Control method: When the above symptoms are found, you can spray 0.5% antiviral agent No. 1 aqueous solution 300x, or 5% juntoxin clear aqueous solution 400-500x for control, once every 7-10 days; spraying 2-3 times in a row will show results.
6. Rust disease
In summer, under high temperature and high humidity, calendula is prone to rust disease. Disease symptoms: diseased leaves develop rust-stained spots, causing leaf drop and poor growth. In severe cases, calendula quickly withers and dies due to massive evaporation of water from within.
Control method: Once the above symptoms are found, the leaves should be promptly removed to reduce the source of disease. In addition, 50% carboxin wettable powder 2000x solution should also be promptly sprayed for control.
That is all I have to introduce about calendula pest and disease control. I believe everyone now knows what to do when calendula gets bugs or becomes sick! Overall, calendula is rarely troubled by pests and diseases, so as long as everyone takes careful care, these troubles will not come knocking.
