Is there a lot of pesticides in broccoli, and what should I do if broccoli is harmed?

Broccoli generally has more pesticides, and generally vegetables like broccoli are liked by pests, so pesticides are sprayed relatively more.

Broccoli (Brassicaceae) generally refers to broccoli. The main base is thick and has a well-developed root system.

The edible part of broccoli is mainly brittle and tender flower stems, short, fat and tender flower sprouts and tightly clustered into globular flower buds. Broccoli has a complete nutritional composition and a fresher flavor than cauliflower. Contains the anti-cancer substance glucose isothiocyanate, which can prevent the growth of cancer cells at an early stage and has special health care effects.

Broccoli is native to Italy. It is widely cultivated in Italy, England, France, and the Netherlands. At the beginning of the 19th century, broccoli was introduced to the United States and later to Japan. It is cultivated in all countries of the world.

Broccoli depends on the region and season, if it is a southern diamondback moth or beet armyworm.

If there are fewer pests in the north in spring, the pesticide is relatively less, on the contrary, there are more pests in autumn, and the amount of pesticide is large. In short, now vegetables are inseparable from pesticides, and now pollution-free pesticides are used more, so wash them well before eating, and it should not be a big problem.

The situation of pesticide residues in broccoli is related to insect repellent and insecticide during the planting process, and the amount of pesticide residues may vary depending on factors such as planting method, type, frequency and quantity of use, here are some possible scenarios:

Broccoli may be grown with pesticides to repel pests. If used frequently or in large amounts, it may lead to more pesticide residues in broccoli.

The amount of pesticide residues may vary depending on the environment, climate, soil quality and other factors of the planting site. For example, soils in some areas may be rich in beneficial microorganisms that are broken down by pesticides, which can help reduce pesticide residues.

The amount of pesticide residues in broccoli can also vary depending on how it is grown. Organically grown broccoli generally has low pesticide residues because organic cultivation does not allow the use of certain chemical pesticides.

The amount of pesticide residues in broccoli can also vary depending on where the consumer buys it. For example, some large supermarkets and retailers may conduct strict quality testing and control on broccoli to ensure that its pesticide residue levels are within safe limits.

To reduce broccoli pesticide residues, consumers can take the following steps:

When buying broccoli, try to choose a reputable and reliable quality supplier.

Carefully wash the surface of the broccoli with mild detergent and water to remove possible pesticide residues.

Broccoli can be soaked in lightly salted water for a while before rinsing with clean water. This helps to reduce pesticide residues and kill pests that may be present.

During the cooking process, broccoli can be heated to help break down pesticide residues that may be present.

In conclusion, the amount of pesticide residues in broccoli can vary depending on a variety of factors. However, by choosing the right purchase channels, the right washing and handling methods, and proper cooking, consumers can reduce the risk of pesticide residues in broccoli.

Dear, hello is a pleasure to serve you If broccoli is harmed, you can try the following methods to solve the problem:1Peeling method:

Use a kitchen knife to gently remove the damaged part, then soak the whole broccoli in salt water for 10-15 minutes, and wait for the sediment to hang on the wall of the pot. 2.Soak in salt water:

Soak the broccoli in salted water for 30-60 minutes, then remove the key hall and put it in clean water, wash it and bury it. 3.Blanch in cold boiled water:

Heat some water to a boil, then blanch the broccoli in hot water for 30 seconds. Then immediately put it into a bowl of ice water to supercool and let it cool naturally to remove harmful substances. 4.

Drip cleaning method: Put the broccoli in a large container, open a small mouth, and let the tap water slowly fall into the drip. In this way, the contaminated part will eventually be cleaned.

The above methods are only for the case of broccoli being damaged by pesticides. I strongly recommend that consumers buy organic, pollution-free and other safe and guaranteed products to avoid the appearance of harmful substances in food and ensure the safety of the diet. If my answer is helpful to you, please give a thumbs up (rate in the lower left corner), look forward to your like, your efforts are very important to me, and finally I wish you good health and a happy mood!

Soaking cauliflower in salt water for a few minutes can help remove pesticide residues. To remove pesticides and for hygiene reasons, blanch them with boiling water. However, a third of vitamin C, folic acid, potassium and active ingredients are lost.

Precautions when cleaning broccoli:

1. When choosing broccoli, the heavier the feel, the better the quality. If you can't roll it, you should also avoid its flower bulbs being too hard, so the broccoli is older. Do not soak for too long when washing to avoid cell damage.

2. The cauliflower should not be left for a long time after it is cut. If cruciferous vegetables are chopped and left in room temperature air for 6 hours, the loss rate of anti-cancer ingredients can reach as much as 75%.

Cabbage vegetables (such as broccoli) have a layer of wax on the leaves and bracts of flowers, which are themselves sparse and watery, and it is normal for water not to seep in.

The leaves of broccoli feel quite oily to the touch, and water droplets on them are easy to roll off, which is blind because there is a waxy layer on it. In addition to the waxy layer, the florets on the flower bulbs of broccoli are also closely arranged, and due to the tension of water, it is also difficult for water to penetrate into such small objects that are arranged closely.

Broccoli, also known as cauliflower (scientific name: ), is a vegetable. It is an annual plant of the Brassica family of the cruciferous family, and is a variety of cabbage along with broccoli (broccoli) and Brussels sprouts.

1. Immersion method.

The purchased vegetables are rinsed with water 2-3 times, and then soaked in clean water for 1-2 hours after selling high to remove the pesticides on the residual surface. You can also add a small amount of dish soap to water and soak it for 10 minutes, which can transfer most of the pesticides on the surface to the dish soap solution. After soaking, rinse with water 2-3 times.

2. Soak in alkaline water.

Many organophosphorus pesticides decompose easily in alkaline environments. The method is to put a small spoon of baking soda in the water, then put the vegetables and fruits into the soak for 15 minutes, remove them and wash them with water.

Summary. 1. When the rosette leaves are formed 20 25 days after planting, broccoli reaches the vigorous period of vegetative growth, and sufficient water and fertilizer must be provided to promote the rapid growth of stems and leaves, so as to lay a good nutritional foundation for the high yield of broccoli in the later stage. In this period, it is necessary to top dressing twice, and the first top dressing is applied to 5-10 kg of high-nitrogen compound fertilizer per mu when the plant begins to grow rapidly (about 15 days after planting); Second, the second top dressing is carried out before the plant ridge sealing, when the heart leaves of the plant begin to twist the heart (about 30 days after planting), combined with weeding in the row between the shallow ditches to apply fertilizer into the soil, 15-15-15 compound fertilizer 20 25 kg per mu.

3. The water should be sufficient in the early stage of the rosette stage to meet the needs of rapid growth and development of plants; When the plants are clumped, squatting (proper watering control to promote underground root development). The side branches that occur in this stage should be removed in time to promote the formation of the main flower bulb.

Inside the ground, what is the cause of the yellowing and drying of broccoli leaves, and what pesticides are used to solve it.

This is not a disease, it is not a pest, and there is no need to use pesticides.

Isn't it sick in the farmland?

There are two main reasons for the yellowing of broccoli, one is that the fertility cannot keep up, and the other is that the soil moisture is insufficient.

The leaves are yellowish. That's why.

1. When the rosette leaves are formed 20 25 days after planting, the broccoli reaches the vigorous period of vegetative growth, and sufficient water and fertilizer must be provided to promote the rapid growth of stems and leaves, so as to lay a good nutritional foundation for the high yield of the orchid in the later stage. In this period, it is necessary to top dressing twice, and the first topdressing is applied to 5-10 kg of high-nitrogen compound fertilizer per mu when the plant begins to grow rapidly (about 15 days after planting); Second, the second top dressing is carried out before the plant ridge sealing, when the heart leaves of the plant begin to twist the heart (about 30 days after planting), combined with weeding in the row between the shallow ditches to apply fertilizer into the soil, 15-15-15 compound fertilizer 20 25 kg per mu. 3. Sufficient watering should be sufficient in the early stage of the rosette stage to meet the needs of rapid growth and development of the modified plants; When the plants are clumped, squatting (proper watering control to promote underground root development).

The side branches that occur in this stage should be removed in time to promote the formation of the main flower bulb.

Fertilizer and water can be avoided by keeping up.

Fourth, in order to promote the transformation of vegetative growth to reproductive growth, which is conducive to the formation of spherical filial piety in spring, nitrogen fertilizer should be properly controlled at this Qiaolu stage, and phosphorus, potassium fertilizer and boron, molybdenum and other micro-fertilizers should be applied. At the beginning of the formation of flower bulbs (40 to 50 days after planting), fertilize once and apply 20-25 kg of high-potassium compound fertilizer per mu. In order to reduce the yellowing of the flower bulb surface and the hollowing of the flower stem, and delay the senescence of the plant, the foliar surface was sprayed with borax and ammonium molybdate solution during the formation stage of the flower bulb, and the spray was sprayed once every 1 week, and sprayed 2 3 times in a row.

During the formation period of flower bulbs, the field soil should be kept moist, and the diseased leaves, old leaves and pests should be removed in time.

Summary. Pro, it is very likely to be infected with downy mildew, downy mildew refers to the plant disease caused by downy mildew in the fungus, mainly harming the leaves, developing from the base to the upper leaves, forming light yellow nearly round to polygonal lesions on the leaf surface in the early stage of the disease, easy to be complicated by horn spot disease, when the air is humid, the back of the leaf produces a frosty mildew layer, sometimes it can spread to the leaf surface, and the later lesions die and are yellow-brown, I hope mine can help you.
