Whitefly is a kind of small phytophagous piercing insect, which is very harmful to sage, it will gradually absorb the juice of its phloem, and because of its strong reproductive ability, it will appear very high density in a very short period of time, so as to absorb a large amount of juice and cause plant weakness.

Control method: when we deal with the diseases and insect pests of this sage, we can spray it with 1500 times EC, which can kill eggs, nymphs and adults.

two。 Aphids

Aphids are a common herbivorous insect with more than 4000 species in the world. Its body length is often less than 10 mm, so it is difficult to find. It will leave honeydew on the leaves of the plant and suck the sap of the leaves, causing the leaves of sage to wither, turn yellow, lose luster, and cause diseases such as coal fouling.

Control method: in view of the diseases and insect pests of this sage, we can directly use 2.5% methamphetamine emulsion 3000 times to spray it.

III. Pest control of sage (disease)

1. Leaf spot disease

Leaf spot is a disease that exists in many plants, and sage is no exception. It mainly harms the leaves, petioles and stems of sage. Many brown spots will appear in the affected parts during the disease, and the spots will spread gradually with the passage of time, and finally lead to the gradual death of the plant.

How to control diseases and insect pests by growing vegetables on the balcony? Vegetables planted in containers, like vegetables cultivated in the earth, may also be attacked by various diseases and insect pests. Attention should be paid to whether the leaves, stems and other organs of vegetables grow well and whether there are pests. Once a problem is found, first of all, it is necessary to distinguish whether it is the problem of environmental conditions such as water, light, temperature or substrate fertility. After excluding these factors, it is determined whether it is a disease or an insect pest. Common problems of growing vegetables in containers and their control measures plants grow too long, slender, and do not result in insufficient light; move the container to a place with sufficient light; excessive nitrogen reduces the nutrient content in the nutrient solution; plants start yellowing from the bottom, lack of vitality, overwatering, too much watering, reducing watering times. Check whether the container has good drainage, insufficient fertility, increase the nutrient content in the nutrient solution, although fully watered, the plant still wilts, drainage and poor ventilation increase the drainage hole of the container, improve the organic matter content in the cultivation substrate, the salt content of the vegetable leaf scorched edge matrix is high, the container plant grows slowly and the resistance is weak when washed with tap water regularly. Slightly purplish low temperature put the container in a warmer place, low phosphate increases the phosphate content in the nutrient solution, the leaves are twisted or engraved with insect pests, spray environmentally friendly insecticides to remove macular, withered, powdery or rust diseases on the leaves, spray environmentally friendly fungicides to determine the occurrence of diseases and insect pests in vegetables, you can refer to the following articles to diagnose diseases and pests, and then go to the horticultural shop to buy pure natural plant health care solution. And prescribe the right medicine. Diagnostic methods of vegetable pests the diagnostic methods of vegetable diseases and insect pests can be identified by the morphological characteristics of pests in different periods, or by the residue of insect pests. The residues of pests such as eggshell, pupa shell, peeling, residual hair and dead bodies, as well as feces, honeydew, silk mesh, foam and so on. First, the leaves are eaten, resulting in engraving. Most of them are eaten by Lepidoptera larvae and Coleoptera pests with chewing mouthparts. Second, wired stripes or gray-white or gray-yellow spots on the leaves. This symptom is mostly caused by piercing and sucking mouthparts pests, such as leaf flies or stink bugs. Third, the seedlings were bitten off or cut off. It is mostly done by crickets or leaf moths. Fourth, secrete honeydew and cause coal disease. These pests cause black spots by producing honeydew-like excreta on the surface of vegetables, often dominated by juice-absorbing and excretory pests, such as a variety of aphids. Fifth, the heart lobe shrinks and thickens. Such symptoms are common on sweet peppers and peppers, which are related to mite pests. Sixth, the body of vegetables is damaged. This kind of pest generally enters the body of vegetables, and it is difficult to see them from the outside. If it is found that there are fresh pest feces on or around the vegetable plant and fresh insect mouth on the vegetable plant, it can be judged that the pest is harmed far away in the vegetable. Sometimes, although there are feces and insect population, but the feces and insect population have dried up, indicating that the pest has moved to other places. Most of these pests are moth pests and larvae. 7. The upper part of the seedling withered and died. This shows that the roots of vegetables are damaged, which are mostly caused by underground pests, such as mole cricket, root mites, root nematodes and so on. 8. The lumpy fruit is eaten and rotted. Such as potatoes, onions, garlic and other underground roots in the growth and storage rot or be eaten, such as nose worms, root mites and so on. In order to judge pests and take corresponding control measures according to these characteristics, we should first eliminate the influence of other factors, such as wilting and death of vegetable seedlings caused by too much fertilizer or water. Many methods of controlling diseases and insect pests of growing vegetables on balcony 1. Catch bugs. It's primitive but effective. Always pay attention to the front and back of the vegetable leaves and the surrounding soil for signs of pests. two。 Quarantine. As soon as you see the branches and leaves that are infected and eaten by diseases and insect pests, you should remove them immediately and throw them for composting. Vegetables that suffer too much damage should be uprooted and thrown for composting. 3. Homemade natural insecticides. There are many simple and effective recipes. An editor of a science magazine once introduced such a method: "when my vegetable garden was suffering from insect pests, I found that some plants around the garden were safe and sound." I picked the branches and leaves of some of these plants, put them in a blender and mixed them with the same amount of water to make a solution. I sprayed the vegetables in the garden with this solution, and it worked very well. " This is because plants that are not affected by pests must contain some kind of disease-resistant and insect-repellent substance. In addition, asparagus juice can kill nematodes that harm tomatoes. Garlic also has a good germicidal and insect repellent effect, which can be ground into powder or squeezed juice to spray on vegetables and seeds. Horseradish also has a strong ability to kill bacteria and deworms, as well as purify the soil. Orange peel, pepper, garlic, mint, marigold, sage, rosemary, salvia and other plants can be used to make insect repellents. 4. Plough the land. Can control ground tiger, cotton bollworm, leafhopper, aphid, mole cricket and other pests. These pests like to lay their eggs on crop stalks or in the soil after harvest in summer and autumn. Therefore, ploughing the land again after autumn harvest and burying the residual stalks of crops in the soil can prevent pests from laying eggs on it. Ploughing the land again before planting in spring will kill most of the remaining pests. The depth of ploughing must be at least 15 centimeters. In this way, you can dig up the eggs, pupae and larvae of insect pests hiding in the ground and let the hot sun, hot wind and natural enemies wipe them out. In our grandparents' time, it was common for egrets and other beneficial birds to follow farmers' ploughs and dig up worms to eat. Nowadays, egrets are seldom seen. However, when ploughing, if you can catch a few chickens and follow behind to eat bugs, it will also have a good effect. 5. Use a protective case to protect the seedlings. Wrap it on the stem of the seedling with brown hard paper, insert it into the soil and expose it to the ground about 3 cm, which can effectively prevent the tiger from biting off the seedling. This method can also be used to deal with cotton bollworm. 6. Sprinkle the flour. In the early morning, sprinkle some flour on cabbage or cabbage leaves while the dew is not dry.

A few days later, in the early morning, shake the cymbals in the bamboo tube into boiling water or gasoline to eliminate. 10. Flush with water. Spider mites can be washed down from vegetable leaves by spraying water with a kettle. Under normal circumstances, they will not go back when they are washed behind. This method can also be used to deal with aphids that harm roses. 11. Scatter plant ash. Sprinkling a circle of plant ash or limestone powder around vegetables can also protect vegetables from ground tigers. But be careful not to scatter ash on the vegetable leaves. twelve。 Putting a bowl of beer next to the plant is said to lure snails and slugs into drowning.

The main results are as follows: (1) vegetable seedlings grow, the plants are slender, and do not bear fruit: most of the reasons are caused by lack of light or excessive nitrogen; the container should be moved to a place with sufficient light to reduce the amount of fertilizer. (2) vegetable seedlings start yellowing, lack of vitality and dark color from the bottom: the reasons are mostly caused by excessive watering and lack of fertility; watering times should be reduced to check whether the container drainage is good or not, and it may also be due to lack of fertilizer and increase the times of fertilization. but do not apply too much at one time, thin fertilizer should be applied frequently. Although fully watered vegetable seedlings are still wilting, drainage and ventilation are poor, the drainage holes of containers should be increased to loosen the soil in flowerpots or planting grooves in time. (3) for the scorched edge of vegetable leaves, most of the salt content of the matrix is too high, so it is necessary to replace the matrix or use large water pressure alkali. (4) the plant grows slowly, the resistance is weak, slightly purple, it should be low temperature, put the container in a warmer place. (5) if macula, withered spot, powder spot or rust spot are found on the leaf or fruit, it is a disease problem, and the diseased part should be removed. If insect bites are found on the leaf, there are irregular insect paths on the back of the leaf, or there are small flying insects on the plant, it is a pest.
