They damage many types of flowers and trees, both Qi Milan woody flower, jasmine, rose, smiling, plum, or herbaceous flowers such as chrysanthemum, geranium, Calceolaria flowers, are spared.
author after years of groping and experiment, take the following lines of various simple easily understood and effective method of anti-harm, not only drawing convenience, and does not pollute the environment. Are presented below, flower lovers should try. Aphids Aphids, also known as armyworms
, have occurred throughout the year, usually around 39 ℃ in temperature breeding the fastest. Many kinds of aphids, usually green, yellow, black, brown in others, damage rose, pomegranate, chrysanthemum,Discount UGG boots, gardenia and other flowers. They gathered at the plant more buds, leaves or twigs. Endless sucking sap, bud damage the heart and flower petals. Yellow foliage plants killed deformation, bud ruined, reduced flowering, Huarong subtractive, severe wilting plants will die. Control methods:
(1) with fresh chili peppers or red pepper 50 grams,UGG shoes, 30-50 grams of water, cook about half an hour, sprinkle with the filtrate affected plants have effects.
(2) with 3-4 grams of detergent, l00 grams of water, stir into the solution, the continuous spray 2-3 times, the control effect of 100%.
(3) with a Kill aphids and scale insects and other pests are more than 95% effect, while the plants will not produce injury.
(4) the detergent, urea, water by the ratio of 1:4:100, stir into the mixture, the use of the sprayed plants, can receive pest control, fertilization double benefit effect.
aphids are major pests of crops, one of many kinds are found to occur algebra, breed quickly, heavy damage. Crop it taking sap to make plants wither weak, and the media are a variety of viral diseases. In agricultural production for the control of the damage, the use of chemical pesticides has become an important tool. However, excessive reliance on chemical pesticides, especially the use of highly toxic pesticides and environmental pollution will produce, leading to excessive pesticide residues in agricultural products, jeopardize the health of people. Therefore, the choice of pollution control measures to control aphid damage is essential. Some aphids are introduced pollution control methods for use and reference.
1, mineral oil spray aphid control: 99% of Green Wing is currently the best in the mineral oil, the main physical effects it can control a variety of worms, with a safe, efficient, ecological and environmental advantages . Aphids by suffocation, to change their behavior (such as the impact feeding, interference winged aphid host location), etc. to achieve effective control of multiple roles, such as oranges, apples in the bud of the use of 100 ~ 200 times, just after the wake of the orange in winter aphid, apple aphid has excellent control effect.
2, mesh cover to avoid aphid: Honda in vegetables and pre-breeding period of 22 mesh gauze with a white cover, anti-winged aphids migrate to avoid damage. Vegetable cultivation in the fall have a good time to avoid the application of disease control aphids (virus disease) effects.
3, yellow sticky trap aphid: yellow, orange and yellow on a wing into a strong trend of aphids can be applied in the yellow panel 10, such as oil or forests where the soil sticky, trapping winged aphids . The size of the yellow board is generally 15 to 20 cm square, hanging or inserted in the field. Yellow plate full of aphids to be induced should be replaced to improve the trapping effect.

4, silver film to avoid aphid: silver-gray aphid repellent strong resistance, can be hung in the field of plastic with a silver or silver-gray mulching crops, anti-aphid migration, have the effect of virus transmission.
5, drive aphid plant cultivation: the smell of leek out volatile repellent effect on the aphid. Leek and vegetables and other crops will be planted with, can reduce aphid population density, alleviate the hazard.
6, aphids off plant sap dip: ① 1 kg of fresh tobacco leaves with 10 kg of water bubble, rub out after tobacco, together with 10 kg of water, rub the fish out, twice a dip then add the juice of 10 kg lime water (containing 0.5 kg of lime) and mix immediately after spraying; ② fresh orange peel 1 kg, 0.5 kg of fresh pepper, a mixture of both mashed and then boiled with 10 kg of water, soak for 24 hours, filtered dip juice spraying, this mixture has a contact action, soon after the death of aphids by the drug, control a significant effect if the aphid; ③ to 1 kg of garlic mash, add equal amount of water, filtered 50 times with water spraying liquid ; ④ take 200 grams of onion slices, soaked in warm water 10 kg,cheap UGG boots, 4 to 5 days after spraying filter; ⑤ fresh dandelion root of 300 grams or 400 grams, its smashed,UGG boots cheap, on the 10 kg warm water of 40 ℃ 1 to 2 hours, filtered juice, when in fruit and leaf spraying of the best; ⑥ other aphid dip juice governance, such as peach leaf, fresh willow, fresh castor leaves, orange juice soaked seeds, etc., have governance Aphid effects.
7, leachate treatment plant ash aphid: 2% to 3% ash leaching solution can prevent fruit aphids.
8, protection and utilization of beneficial natural enemies: grass cultivation methods adopted, in favor of Coccinella septempunctata, Harmonia axyridis, lacewings, flower bugs, hover flies, aphid parasitoids, spiders, fungus and other natural enemies of aphids habitat for reproduction. Natural enemies in the main breeding season, attention to coordination of defense, reducing the number of drugs, choose low-toxicity pesticide spraying and other measures to give full play to the role of natural enemies in controlling pests.
