Flowers and trees common three pest control methods

"Aphids, red spiders, scale insects"
It is the three most common pests that harm flower trees. These three pests can be harmed in a variety of flowers and trees (such as woody flowers Milan, jasmine, Chinese rose, smiling, plum, herbal flowers chrysanthemum, geranium, Pouchao, etc.). The occurrence of locusts, red spiders, and scale insects in flowers and trees not only affects their growth and development, but also causes damage to the leaves and flowers of flowers, which makes them lose their ornamental value. Therefore, timely measures should be taken to prevent and control it. The following describes the three common pest control methods for reference.
Insect locust damage characteristics: Aphid is a kind of pest most harmful to flower seedlings (seedlings), in the tulip, peach, cherry, oleander, plum, hollyhock, orchid, and Solanaceae, cruciferous, Cucurbitaceae and other flowers It happened. It sucks a lot of sap from the seedlings by sucking and sucking mouthparts, stagnating or delaying its growth, severely causing abnormal growth, inducing coal pollution, and spreading various plant viruses.
Control methods:
1 Use 50 grams of fresh hot pepper or dry red pepper, add 30 grams to 50 grams of water, boil for about half an hour, and spray the affected plants with their filtrate. 2 Use detergent 3g-4g, add 100g of water, stir into a solution, spray 2 times -3 times. 3 Use 600 times-800 times fluid with Fengyoujing water. Spray the insect pests carefully with a sprayer to make the insect body stained with liquid medicine. The effect of killing the aphids and scale insects is above 95% without causing any harm to the plants. . 4 Mix the detergent, urea, and water in a ratio of 1:4:100 and stir them into a mixture. Spray the plants and receive the effects of extermination and fertilization. 5 can also be used to control aphids of specific drugs such as 1.8% avermectin (Insect grams) 3000-5000 times, 10% imidacloprid WP 2000 times, 50% anti-inverse Wei wet powder 1500 times - 2000 times liquid spray. The focus of the spray is the growth point and the back of the blade.
Red spider damage: Red spider is also called short beard, which mainly damages the leaves and flowers of flowers. The wild pheasants, querque, and pine needles in bonsai are also vulnerable to its harm. The sucking stems and leaves juice reduced the moisture of the affected parts, showing chlorosis and whitening, and the leaves surface showed dense and pale spots and curled yellow. Plants with yellow leaves, charred leaves, leaf curls, deciduous leaves, and death appear to be serious. At the same time, Starscream is the mediator of viral disease.
Control methods:
1 Soak citrus in water for about 24 hours with water and filter the plants with filtrate. 2 Take 50 grams of grass ash plus 2500 grams of water, stir well, soak for 48 hours, then filter, add 3 grams of detergent and mix thoroughly, spray, spray once a day, even for 3 days, every other week for another 3 days. 3 Use a lighted mosquito coil on a plate, place it in a diseased pot, and then use a plastic bag to fasten the pot and smoke it for about 1 hour. Adults and eggs can be killed. 4 When spider mites occur in large numbers, 20% dicofol EC can be used 500 times to 600 times, or 20% chlorimethanol 2000 times to spray 2 times.
Scale insect damage characteristics: scale insects are one of the most common pests on flowers, rose, rose, hibiscus, bergamot and more expensive flowers osmanthus, peony, camellia and other flowers occur. Damaged plants, light yellow leaves, withered, and easy to induce soy disease, affecting growth and appreciation; in serious cases, the whole plant decline and death.
Control methods:
The insect body of the scale insect is surrounded by a layer of keratinous shells, and it is difficult to be effective if the medicine is used in general. Experienced flower workers take the following methods to work well. 1 Use white wine to water in a ratio of 1:2. When pests are infested, pour the surface layer of potted soil. 2 Use vinegar (rice vinegar) 50 ml, soak the small cotton balls in vinegar and wipe them with a wet cotton ball on the damaged stems and leaves of the flowers to wipe off the scale insects. This method is convenient and safe. It can not only achieve the purpose of removing insects, but also make the damaged leaves return green. 3 When the diseased branches are gently rubbed with alcohol, the scale insects can be removed, which is invisible to the naked eye, and can be completely destroyed. The scale insects are rarely found in the second year. 4 If a few scale insects are found on individual branches and leaves, you can use a toothbrush to remove them, or you can wear gloves. Carefully remove the scale insects on the shoots, or combine plastic surgery to remove the insect leaves and branches.
