The chrysanthemum, also known as the thousand lotus. It is beautiful and colorful, and there are less blue flowers in the flowers, full of flowers, is a typical winter and spring potted flowers. Because it is cultivated in the greenhouse, indoor potted plants are more crowded, combined with high temperature and poor ventilation, which provides favorable conditions for the breeding of pathogens and the survival of certain pests. At the same time, pests can also enter indoor through vents, etc. From the beginning of seedling stage, we must pay attention to the prevention and control of related pests and diseases.
1. The danger of red spider spider mites to cineraria began in March, when the greenhouse temperature was dry. Adult females after wintering begin feeding for spawning, and they usually infest around the main veins of the back of the leaves. On the front of the victim's leaf, the whitish white spots are initially visible, gradually turning red, and the screen on the back of the leaves will eventually fall off. The earliest prevention should be in the winter to ensure that the surrounding environment of the cineraria is clean, remove weeds and leaves in time, check the basin soil, and eliminate the source of overwintering insects. In the period of insect infestation, if the cineraria has not budded and blossomed yet, 2000 times of 40% triclosan emulsion or 40% omethoate 1000 times will be sprayed every 7 days for a total of 2-3 injections. The effect is better; if the cineraria is Blooming flowers, in order to avoid sensitive flowers, try not to spray pesticides. Foliar spray can be used to flush or use chewing gum to remove pests, but also use some natural plants such as garlic, scallions, pepper and other leaching blister several days after the leaching solution with a suitable amount of neutral detergent spray treatment.
2. Aphids The worms are small, fast-growing, and multiply clustered on the backs and stems of the cineraria. The damaged leaves turned yellow and curled to the back. In general, the warm winter season, spring warmer early, and rainy year, began to damage in March. Because the locusts overwinter over eggs on the cineraria, after checking the plants in the winter, the plants were sprayed with Baume sulfur at 5 degrees to eliminate the overwintering eggs. Spray 40% omethoate 1200-2000 times or 40% acephate 1000-fold solution during the locust infestation period. In order to avoid phytotoxicity during flowering period, phytochemicals such as 3% natural pyrethrin, 25% rattan extract, and 40% sulfuric acid extract can also be used. They can be diluted to 1000-1500 times.
3. The poisonous moth moths are mainly larvae and are often referred to as poison caterpillars. The larvae of the first-instar larvae are harmed and eat the leaves and leave the epidermis, which resembles a skylight. Slightly larger poisonous caterpillars are dispersed and bite the leaves into nicks and holes. The entire plant began to suffer from the lower larger leaves. Insect pests began to peak in April, when the temperature in the greenhouse stabilized at about 20 °C. If you take drug control, you can use 50% or 50% of phoxim and spray 1000 times. But at this time, the geranium is usually at flowering, and only manual hunting is safer. It is worth noting that poisonous caterpillars are toxic to human skin and can cause dermatitis. Therefore, gloves must be used for catching with ticks to prevent them.
4. Powdery mildew cineraria is most susceptible to powdery mildew, which is a widespread fungal disease. White sticky material appeared on the front of infected leaf blades, curled and deformed, withered and falling off. The easiest way to prevent it is to ensure adequate lighting and timely ventilation. If the disease has already occurred, it is necessary to use a 1000-fold 70% thiophanate-methyl solution or a 2000-fold 50% dexamethasone solution in the initial stage, or use 25% triadimefon-based WP 2000 times to control the condition. . At the same time, diseased leaves are cut off and destroyed, and diseased plants and healthy plants are separated so as to avoid mutual infection and aggravate disease spread.
5. Root rot and stalk rot In the winter, the water in the guayule pot soil is not easy to dry. Poor drainage, insufficient indoor light, and excessive air humidification can cause root rot and stem rot. . The roots and stems are black and rotten. Prevention and control methods First, pay attention to ventilation and humidity, and increase light after watering. The second disease of the cineraria, cut off the disease, apply sulphur powder, replace the loose culture soil and replant.
In a word, the prevention and control of pests and diseases of cineraria are mainly prevention. Only by knowing the time and regularity of the occurrence of pests and diseases, and before adopting proper protective measures, we can minimize the damage of pests and diseases and effectively improve the ornamental effect of cineraria.
