What to do with the rattan water spinach scale insects that you eat?

At this time, we can spray some imidacloprid, which can also play a role in controlling scale insects, and you can eat it after a week.

What should I do if I eat water spinach and how many worms grow? You should wash it and wash it several times, preferably with salt, and then blanch it with boiling water after washing.

If you talk about this species, then you can't ask for this dish, because it is risky to eat, and this dish grows very fast.

Sometimes, green food is still needed.

Water spinach worms can be mixed with washing powder with water, stirred evenly and then put into a watering can, spray on water spinach, can poison the seeds and die. You can also light mosquito coils next to water spinach, mosquito coils will produce harmful gases to insects when burned, which will kill pests.

First, the maintenance method.

1. Temperature: Water spinach likes a warm environment, the cold-resistant nature is not very high, the temperature in winter needs to be kept above ten degrees, and at the same time it can withstand a certain high temperature in summer, so there is no need to do too many measures in summer.

2. Watering: The normal growth soil needs to be moist enough to replenish water in time, and more watering can make the growth rate of the plant faster, so that the yield will naturally increase a lot. Drought tolerance is very low, so try to avoid dryness.

3. Light: The normal growth of water spinach needs to maintain sufficient light, so that it can photosynthesize, and the branches and leaves will grow more tender and green, if the light is not enough, the branches and leaves will become very short, and the color will not achieve the expected effect.

4. Fertilization: fertile soil can grow ideal plants, water spinach is no exception, during the growth period need to apply some high-nitrogen water-soluble fertilizer, so that it can fully absorb nutrients. Of course, the amount of fertilizer should not be too much, and it is necessary to pay attention to thin fertilizer and frequent application.

Second, breeding skills.

1. Reproduction: sowing is the main way of reproduction of water spinach, before sowing the seeds to soak in water for a day, and then you can sow seeds, after sowing to gently cover with soil, and then keep the soil moist, at the same time the temperature does not need to be too high, keep the environment warm enough, wait for germination after transplantation.

2. Pruning: Water spinach does not need to be pruned, only the yellowed branches and leaves need to be removed, and diseased branches and leaves may occur in the case of poor growth care, so they also need to be cut off, and the others almost do not need to be pruned.

Water spinach insects can be sprayed with pesticides to remove insects, and the leaves of the insects should be removed when eating, and then washed with water before eating. Water spinach likes high temperature and humidity environments, which is also the reason why it is easy to get insects. When water spinach grows insects, it eats the leaves, and if you look closely at the leaves where the insects are found, you may also find eggs.

Therefore, the leaves of the insects should be removed and washed with water before eating.

Your water spinach has worms, if the water spinach has worms, then it must be sprayed, if the hollow is not sprayed, then it will not die if it grows worms, so if the water spinach has worms, it must be sprayed.

I've got bugs on my water spinach. What to do? Spray pesticides, such as: trichlorfon, dichlorfon, pesticides are generally toxic to people, and must be used in strict accordance with the instructions.

If there are a lot of bugs growing on your water spinach, try not to eat the water spinach and throw the water spinach the best.

Water spinach is very susceptible to insects, so you can dilute it with some pesticides and spray it on the leaves.

The water spinach is heavy, which can buy that kind of specialized politics, and his kind of medicine will be good if it is hit.

Hand catch or spray avermectin.

In general, when cabbage begins to form balls, there will be water stains on the outermost leaf or at the bottom that make it look like a blister. At first, the outermost leaf is dying only at noon, and returns to its original state in the morning and evening. After a long time, it can no longer recover, and it begins to rot.

The rotten place is particularly severe, like the rotten leaves that have been frozen in the refrigerator, all of them are pureed, and even give off a rotten smell. It's not just the outer leaves that rot, it's also the whole leaf that's rotten.

The degree of pesticide residues in cabbage is second only to leeks, and it is also related to its very easy insecticide. There is a bug called "burrowing worm", as the name suggests, it is a worm that burrows into the innermost layer of cabbage. In order to kill insects, vegetable farmers have to use highly toxic pesticides to repeatedly "fill the heart", resulting in an increase in pesticide residues.

Kale (Brassica oleracea L.).): is an annual or biennial herbaceous plant of the cruciferous family, Brassica genus, a biennial herb, powdered with frost.

Short and stout annual stems fleshy, unbranched, green or grayish-green. The basal leaves are thick, wrapped in spherical layers, oblate spherical, milky white or pale green; The biennial stem is branched and has stems and leaves. basal leaves rounded at the apex, narrowed to very short petioles with broad wings at the base, undulating margins without distinct serrations; The upper stem leaves are ovate or oblong-ovate, and the base holds the stem; The uppermost leaf is oblong, about centimeters long and 1 centimeter wide, hugging the stem.

racemes apical and axillary; The flowers are pale yellow, centimeter in diameter; peduncle 7-15 mm long; sepals erect, linearly oblong; The petals are broadly elliptic-obovate or nearly rounded, slightly absent at the apex, and the base is abruptly narrowed into claws, 5-7 mm long. The long-horned fruit is cylindrical, slightly flattened on both sides, the midrib is prominent, the beak is conical; The fruit peduncle is thick and spreads erect. The seeds are spherical and brown.

The flowering period is April, and the fruiting period is May.

It is cultivated all over China for vegetables and feed. The thick juice of the leaves is used for gastric and duodenal ulcers. It is one of the important vegetables in China.

With the exception of kale, which is native to China, various varieties of kale originate from the Mediterranean Sea to the North Sea coast. As early as 4000-4500 years ago, the ancient Romans and ancient Greeks cultivated it, and it was commonly known as "kohlrabi" in Northeast China and "lotus white" in Yunnan.

This small dot is a scale insect egg.

Scale insects prefer an environment of 25-30 and prefer humidity, so it is easy to break out in the rainy season of summer. It is also afraid of dryness, and a large number of deaths will occur in a dry environment in winter.

The spread of scale insects is very fast, male insects have wings and can fly, in addition to the wind is also the main way of transmission of scale insects. If there is a scale insect in your home, you must eliminate it as soon as possible, otherwise you will soon find that most of the plants in your home have scale insects.

Lettuce is a green vegetable with high nutritional value, which can be both soil and hydroponic, and is relatively simple to grow. Lettuce can not only be stir-fried, but also blanched and dressed, with a delicate and smooth taste.

Agricultural prevention and control: 1. Try to avoid continuous cropping and implement crop rotation. After the harvest of the previous crop of vegetables, it is necessary to plough and dry the furrow in time, remove the debris and weeds in the field, and remove the damaged leaves of Heling in time to reduce the source of honey insects.

Honey insects like to eat carbohydrates, in the process of vegetable cultivation, to use more rotten farm fertilizer, as little as possible to use chemical fertilizer, especially not too much fertilizer at one time, to avoid vegetable leaves thick green, long, soft tissue, plant carbohydrates in the body of the sudden increase, honey worms in a short period of time to break out.

2. Natural enemies control aphids. There are many kinds of natural enemies of honey worms, mainly seven-star ladybugs, heterochromatic ladybugs, grass clams, aphid flies and aphid molds, these beneficial natural enemies should pay attention to protection and utilization, that is, a large number of pests can be eliminated, so that the population of honey worms can be controlled within the number of inadequate harms.

When there are not many honey insects in the field and there are a certain number of natural enemies, do not use pesticides, so as not to harm the natural enemies, destroy the ecological balance, and attract honey insects. When honey insects reach the control index and need to be medicated, they should also be used in the damaged parts of the plant, such as the growth point of the plant, young leaves, young stems, leaf backs, etc., so as to achieve a targeted goal and fully protect the natural enemies.

3. Yellow plate to trap aphids. Winged adult aphid has a strong tropism to yellow and orange-yellow, and the size of 15 20 cm yellow cardboard can be made in production, and it is best to coat a layer of No. 10 engine oil or pesticides commonly used to treat aphids on the cardboard, and insert or hang it between the rows of vegetables and the same level as vegetables. After the oil yellow plate is full of aphids, it should be replaced in time, and the drug yellow plate will make the honey worms die when they touch the medicine.

4. Silver ash film to avoid aphids. Silver gray has a strong resistance to honey insects, and can be hung in the field with silver gray plastic strips or covered with silver gray mulch.

5. Urine wash mixture to kill aphids. Press urea, laundry detergent and water 1:4:

The ratio of 100 is made of urine lotion mixture, evenly and thoughtfully sprayed on both sides of the front and back of the leaves, spraying 30 kg of liquid per mu, spraying 2 3 times. It not only has a good control effect on vegetable honeyworms, but also has the effect of foliar fertilization to promote growth. However, the "urine lotion mixture" should be prepared and used to prevent the failure of urea volatilization.

<> agricultural control of water spinach leaf curl insects: overwintering larvae can be lured by piling grass, burned, and overwintering larvae in fallen leaves and cracks can also be killed in autumn and winter, and the damaged leaves can be removed in summer. Pharmaceutical prevention and control:

At the end of the second instar of the larvae, before the leaves are rolled, spray 1000 times of 25 imidothion EC and 1000 times of 50 phoxanthion EC.
