I have worms on my water spinach, what should I do?

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.

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.

If there is green in the empty book, it is the larva of the vegetable blind and hungry butterfly.

But if you're sure it's absolutely white, there's a good chance it's maggots. They sometimes eat water spinach when they are short of food mill returns.

Look

1. Clean up the garden or vegetable field in time.

After the cabbage is harvested, it is necessary to remove the residual plants and leaves in the field in time, and plough the land to eliminate the eggs and larvae attached to the cabbage. Once it is found that the leaves of cabbage are eaten, the missing leaves should be removed in time, and attention should be paid to reducing the density of insects in summer to reduce the damage of cabbage.

2. Choose the right variety.

When selecting cabbage, it is advisable to choose varieties with a short growth period, and growers can also cooperate with cultivation techniques such as plastic film mulching to make the harvest date of cabbage advance, avoid the peak period of large green worms, and reduce its harm.

3. Do a good job in field management.

After the cabbage is harvested, it is necessary to seize the time to renovate the soil and eliminate the source of insects. The cabbage green worm is mainly prevented, and it can be manually captured and eliminated when it occurs.

4. Physical prevention and control.

There are more than 70 known natural enemies of large green worms, such as the red-eyed wasp at the egg stage, the butterfly cocoon wasp at the larval stage, the butterfly pupae golden wasp at the pupal stage, and the large legged wasp. Predatory natural enemies include wasps, cryptopteras, hunting bugs, wasps, flower bugs, beetles, grassy ridges, ladybugs, spiders, etc., and growers can use natural enemies to control them.

5. Biological control.

Dilute 500 700 times the solution with bacillus borer or green worm fungus (8010 billion spores per gram), and use 50 kg of bacterial solution per mu.

6. Pharmaceutical prevention and control.

1) Spray with trichlorfon powder or 2% carbaryl powder, spraying about 2 kg per mu.

2) Spray with 90% crystalline trichlorfon 800 1000 times, or 45% malathion EC 1000 times, or 50% phoxanthion EC 1500 times, or deltamethrin emulsion 5000 times, spray about 75 kg per mu.

This is the aphid, aphid, also known as greasy insects, honey worms, is a class of herbivorous insects, including all members of the family Aphidoidea (also known as the family Aphidoidea). There are about 4,400 species of aphids in 10 families, most of which belong to the family Aphididae.

Aphids are also one of the most destructive pests on the planet. About 250 of these are pests that are serious for the agroforestry and horticulture industries. Aphids vary in size, ranging from one to ten millimeters in length.

The natural enemies of aphids are ladybugs, aphid-eating flies, parasitic wasps, and aphid-eating gall mosquitoes.

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.

Control of Spodoptera exigua.

Abamectin is available.

3000 times liquid; Control of diamondback moth and cabbage worm.

1000 1500 times of Caixi suspension can be used.

1. Prevention and control measures:

Clean the field: After harvesting, remove the residual plants and leaves in the field in time and burn them intensively to reduce the density of insect population.

Manual capture: It is easy to catch larvae and pupae and adults, and adults can be caught with nets for good results.

Protection and utilization of natural enemies and insects: There are many natural enemies of cabbage insects, such as golden wasps and large legged wasps parasitic on pupa; Parasitic on the larvae are yellow velvet wasps; Parasitic on the eggs are the broad-eyed wasp; There are also predatory curls and wasps.

and parasitic bacteria and fungi.

Virus. The above natural enemies play a great role in inhibiting insect populations. This method protects both insects and the environment.

Reduce pesticide pollution.

Pesticide control: due to the serious overlapping of generations of cabbage insects, the larvae after the third instar have increased their food consumption and drug resistance.

Intensifier. Therefore, the application should be before the second instar, and the agent can be sprayed with 1 000 times of 40% Xinnongbao EC, or 3 000 times of enemy EC, or 1 000 1 500 times of Tianwang Baishu EC, or 1 000 1 500 times of Caixi suspension.

2. How to manage the heart-to-heart period of Chinese cabbage:

After the Chinese cabbage enters the core stage, ensure that the soil has enough moisture to prevent the soil surface from drying and cracking. The water consumption of Chinese cabbage in the core stage is larger than that in the previous period, and it must be irrigated to replenish to keep the water uniform and sufficient. In particular, the leaf moisture content of Chinese cabbage accounted for 95 96, so it was particularly important to strengthen the water management at the core stage.

The specific requirements are: the first water in the centering stage should be small, and too much water will cause plant growth damage; After 4 5 days of the first water in the heart of the core into normal irrigation, generally 5 7 days of one water, each irrigation water volume is not less than 30 square meters; Stop watering a week before chopping, one is to avoid too much water and is not resistant to storage, and the other is to facilitate cutting and harvesting, reducing losses caused by mechanical damage.

Timely topdressing: In order to reduce the mechanical damage caused by manual operation after entering the core stage, the top dressing should be mainly applied with water, the first top dressing is applied before the cold dew, and the second time is topdressing a few days before the frost. During this period, the temperature gradually drops, and the topdressing fertilizer should be mainly fast-acting nitrogen fertilizer, which can be applied with Ribery Yanwo high-nitrogen water-soluble fertilizer and washed with water.

The amount of topdressing should be appropriately increased for plots with a slightly worse degree of wrapping. In the later stage, top dressing should be stopped to avoid the growth of Chinese cabbage.

Pest control: According to the main species of pests and diseases, refer to the corresponding control methods to select pesticides, and seize the favorable opportunity before the Chinese cabbage ridge sealing for control. Half a month before the Chinese cabbage is harvested, the drug should be stopped. During the heart-wrapping period of Chinese cabbage, it is necessary to focus on the prevention and control of downy mildew.

Black spot, soft rot, black rot, bacterial horn spot, aphids.

cabbage worm, beet armyworm, etc. It is required to use symptomatic drugs, and the prevention and treatment is scientific and timely. The spraying should be thoughtful and meticulous, and it is advisable to spray both the front and back of the leaves. Chemical control and physical control are combined, and insecticidal lamps or yellow plates can be used to trap and control insect pests.
