Common pest and disease control methods for anemones, chemical control works fast
Pests and diseases are the most unwelcome problems in the process of plant growth, and anemones are no exception. Such problems are extremely harmful to the plants, not only affecting their ornamental value, but in severe cases also causing the plants to wither and die. What should be done about the common pests and diseases of anemones and their control? Below, the editor will walk you through it.
Common pests and diseases of anemones and their control
If you want to know what to do about the common pests and diseases of anemones and their control, first we need to identify exactly which pest or disease it is based on the symptoms, and then carry out targeted treatment, because the control methods for each pest and disease are different. The details are introduced below, and friends troubled by this can take a look.
Aphids
Aphids are one of the most destructive plant pests worldwide, harmful to the vast majority of plants, and anemones are one of them. This pest sucks the sap from the leaves, stems, tender tips and tender ears of the plant, causing a massive loss of nutrients, and finally the plant gradually withers and dies.
Control method: For this pest and disease of anemones, the most direct method is to directly use chemicals to spray and kill them. In terms of chemicals, we can use 50% pirimicarb wettable powder at 3000 times dilution or 50% malathion emulsion at 1000 times dilution.
Cutworms
Cutworms are a pest of the Noctuidae family, Lepidoptera order. Every spring is the peak period for this pest, so everyone should pay extra attention in this season. This pest generally hides in the soil during the day, and comes out at night to feed on the tender stems of anemones. If left untreated for a long time, it will cause the plant to wither and die.
Control method: When dealing with this pest and disease of anemones, we can use 80% dichlorvos or 50% phoxim mixed with water and then apply it as a root drench to the plant, in order to kill this pest.
Thrips
Thrips is the collective name for the order Thysanoptera of the class Insecta. This pest mainly harms the branches and tips, leaves, flowers and fruits of anemones. The damaged leaves and branch tips will show symptoms of hardening, curling and withering, and after the fruit is damaged it will harden, and in severe cases it will also affect the fruit yield.
Control method: If anemones are harmed by this pest, we must carry out control in time. The most direct control method is that we can use 25% thiamethoxam Dagongniu at 3000-5000 times dilution to directly spray and kill them.
Rot disease
Rot disease is a disease caused by fungi. This is a disease that can both infect young seedlings and occur during the flowering period. It can occur on the flowers, fruits, leaves and stems of anemones. If this disease is not treated in time, it will cause the plant to gradually wither and die.
Control method: When dealing with this pest and disease of anemones, we can use 40% procymidone wettable powder 15—20g to treat the diseased plants, generally once every 3-5 days, and after 2-3 times it can be cured.
Downy mildew
Downy mildew refers to a plant disease caused by downy mildew fungi. This disease can occur from the seedling stage to the harvest stage. When it occurs, many light yellow nearly round to polygonal lesions will form on the leaves of anemones, and the lesions will gradually spread, finally causing the plant to wither and die.
Control method: When dealing with downy mildew, if the damage is relatively light, we can use 400-600 times dilution of HILOT Kai Frost diluted for spraying to control it. If the condition is more serious, we need to use 100-300 times dilution of HILOT Kai Frost for spraying.
Powdery mildew
Powdery mildew is a condition caused by infection with powdery mildew fungi. When it occurs, many white powdery lesions will appear on the leaves of anemones, and as time goes on they will gradually cover the entire leaf surface, causing the plant to be unable to carry out photosynthesis and gradually shrink and die.
Control method: If we find symptoms of powdery mildew on the plant, we must deal with it immediately. When treating, we can use triadimefon at 800 times dilution for spraying to treat the plant, generally once every 7-8 days, and generally after three consecutive sprays it can basically be cured.
Common pests and diseases of anemones and their control
The pests of anemones and their control
The main pests in anemone cultivation are three kinds: aphids, thrips and cutworms. When controlling the pests of anemones, commonly used insecticides can be used for control. Before planting, the soil can be strictly sterilized, which can reduce the occurrence and spread of pests to a certain extent.
The diseases of anemones and their control
The common diseases of anemones include rot disease, damping-off, gray mold and powdery mildew, etc.
Rot disease
Rot disease usually occurs and spreads under humid conditions. It is a disease caused by Pythium. Rot disease can cause germinating seeds to rot or the roots of the plant to become diseased, and then the roots and stems will show water-soaked rot, causing the plant to grow slowly or even die. To control rot disease, the first thing is to sterilize the soil. You can mix quintozene or soil fungicide-insecticide with the seeds, and mix it into the soil to sterilize and disinfect. If the disease has already occurred, you can use Tuzet for spray sterilization.
Damping-off
It is caused by Rhizoctonia. Its symptoms are that the leaves turn brown, and the sunken areas become more obvious. Diseased plants will produce tea-colored round-spot-shaped mycelial masses. To control damping-off, Chipco 26019 can be used to kill it.
Gray mold
It is a disease that can both infect young seedlings and occur during the flowering period. It is mainly because relatively high air humidity and a water film on the plant surface promote infection of the plant by Botrytis cinerea. To control gray mold, chlorothalonil and carbendazim can be used for spray killing.
Powdery mildew
The cause of powdery mildew is infection by powdery mildew fungi. Its disease symptoms are mainly that the leaves curl in a spiral shape, and there are round white spots on the leaves, stems and flower buds. In severe cases, it will cause the flower buds to stop growing. Spraying with triadimefon at 800 times dilution can control this disease. If the condition is serious, spray again after 7-8 days, and three consecutive sprays can basically bring it under control.
Control methods for common pests and diseases of anemones
The most common diseases of anemones include rot disease caused by Pythium, damping-off caused by Rhizoctonia, gray mold caused by Botrytis cinerea, and powdery mildew caused by powdery mildew fungi.
1. Rot diseaseIt is a disease that can be caused by several kinds of Pythium. It can occur regardless of whether the temperature is high or low. Under humid conditions, rot disease is more likely to occur and spread. It can cause germinating seeds to rot or the roots of the plant to become diseased, causing the plant to grow slowly or even die. After infection by Pythium, the roots and stems of the diseased plant will show water-soaked rot.
Control method:
First, thesoilshould be sterilized. You can use quintozene or soil fungicide-insecticide to dress the seeds, and mix it into the soil to sterilize and disinfect. If the disease has already occurred, you can use Tuzet for spray sterilization.
2.Rhizoctonia can causedamping-off. This pathogen likes warm and humidenvironments. Compared with rot disease, its symptoms are brown, and the sunken areas are more obvious. Sometimes tea-colored round-spot-shaped mycelial masses can be found at the part where the diseased plant meets the substrate.
Control method:
MedaIIion and Chipco26019, etc. can be used to kill it.
3. Gray moldIt is a disease that can both infect young seedlings and occur during the flowering period. Relatively high air humidity and a water film on the plant surface can promote infection of the plant by Botrytis cinerea.
Control method:
For this disease, Mancozeb can be used for spraying, or chlorothalonil and carbendazim can be used for spray killing.
4. Powdery mildewIt is a condition caused by infection with powdery mildew fungi. Its damage symptoms include spiral curling of the leaves, and round white spots on the leaves, stems and flower buds. The damaged flower buds cannot bloom correctly, curl, and stop growing.
Control method:
Immediately use triadimefon at 800 times dilution for spray killing. If the condition is serious, spray again after 7-8 days, and three consecutive sprays can basicallybring it undercontrol.
