What Pesticides to Use on Apple Trees for Better Growth and High Yield
The editor will discuss the topic of what pesticides to use on apple trees for better growth and high yield in the field of green plants and flowers. Let's proceed with the introduction.
What Pesticides to Use on Apple Trees for Better Growth and High Yield
If you want the fruits of apple trees to grow well, it is important to regularly apply pesticides. Common growth regulators include auxins, gibberellins, ethylene, cytokinins, abscisic acid, brassinolide, salicylic acid, ketone acid, and polyamines. These six types of agents can protect the flowers and fruits of apple trees. If you want apple trees to bloom early and produce more flowers, you can apply pesticides such as DuPont Fortune, Nisolan, Aitoshou, and XuleBOR before blooming, which can be chosen based on actual conditions.
Growth Cycle of Apple Trees
1. The first stage in the growth process of apple trees is the seedling growth stage. 2. After sufficient nutrients, the trees start to differentiate into flower buds, gradually entering the flowering stage. 3. Apple trees usually enter the flowering stage between April and June. It is necessary to ensure sufficient water before flowering, and stop watering during the flowering period. 4. The physiological fruit drop stage is an important period in the growth process of apple trees, which usually occurs in June every year.Pesticide Application on Apple Trees
During the growth process of apple trees, round, deep red spots may appear around the lenticels on the branches. In severe cases, the bark may crack and appear rough. The general control method is to scrape off the spots on the trunk when they are found. From May to the first ten days of June, protective agents such as aluminum trisulfonate·polyoxomanganese, mancozeb, Bordeaux mixture·mancozeb, and basic copper sulfate are sprayed. Viral invasion and initial protection agents and therapeutic agents are mixed: such as triadimefon·ethyl alliumin, thiabendazole·mancozeb, isoprothiolane·polyoxomanganese, tebuconazole, and picoxystrobin·fluor硅azole, etc.Common growth regulators for protecting flowers and fruits of apple trees include auxins, gibberellins, ethylene, cytokinins, abscisic acid, brassinolide, salicylic acid, ketone acid, and polyamines. These six types of agents can protect the flowers and fruits of apple trees. What pesticides to spray on apple trees for faster growth should be done during the flowering period in April, when the entire garden is sprayed with insecticides and fungicides three days before the flowers. This can promote their growth. What pesticides to use for early and abundant blooming of apple trees can be done by applying DuPont Fortune, Nisolan, chlorpyrifos, Aitoshou, and XuleBOR before flowering. DuPont Fortune is used to prevent various diseases, Nisolan and chlorpyrifos are used to eliminate overwintering eggs, Aitoshou can prevent cold, and XuleBOR can supplement nutrients and promote flowering and fruit setting. What pesticides to use on apple trees to prevent pests includes controlling diseases such as ring rot and rot, and overwintering pests such as aphids, mites, and scale insects, by applying 9281 or strong ring rot net 5-10 times liquid. For severe aphid orchards, spray 40% imidacloprid emulsion 1500 times liquid. A strong渗透 assistant killer can be added during the application of the pesticide.
Apple Tree Disease and Pest Prevention
1. Manual control: In combination with cultivation management, eliminate diseases and pests through fertilization, soil turning, pruning, and thinning of flowers and fruits, or manually capture, remove, and scrape off pests based on their occurrence characteristics. This method is widely used in production and is almost used for the control of every type of pest and disease.2. Chemical control: Spray 90% trichlorfon 1000 times liquid or 50% dichlorvos emulsion 800-1000 times liquid under the plastic sheet; if the larvae have climbed the tree, spray 50% phoxim emulsion 1000 times liquid or pyrethroid insecticides to eliminate the larvae before they reach the third instar. For severe cases of Apoecetes glabrirostris, manually capture them in the early morning or evening. When the situation is serious, spray the entire tree with 50% phoxim emulsion 1000 times liquid or 50% parathion emulsion 2000 times liquid.The above introduction to what pesticides to use on apple trees for better growth and high yield is provided for everyone's enjoyment!
