Sling the bull! Water spinach is pesticide-free.

The rankings are as follows:
1.Tomato. Tomatoes grow in greenhouses, and their stamens cannot pollinate and bear fruit normally, so vegetable farmers generally put some growth regulators on the pistils so that it can grow tomatoes.
When choosing tomatoes, choose one with a round appearance, small white spots like sand on the surface, and a little crack on the tail, which means that the tomatoes are naturally growing and ripe.
2.Cabbage. In the course of the growth cycle of cabbage, at least two drugs should be injected.
The first should be beaten on the roots of the cabbage, avoiding maggots from eating the roots of the cabbage. If you don't take this medicine, the maggot will bite off the root of the cabbage, and the cabbage will not grow. Another medicine needs to be applied to the leaves of cabbage, which is to prevent normal insect infestation.
3.Cauliflower. Because the cauliflower is relatively tender, it is easy to bump and hurt the appearance during transportation, so after picking, vegetable farmers often wrap a layer of paper or net-like film on the cauliflower, which causes the medicine on the cauliflower to be volatile.
In addition, because the surface of the cauliflower is uneven and difficult to clean, it remains in the cauliflower.
4.Cucumber. I believe that many people like to pick "top flowers with thorns" when buying cucumbers, thinking that they are relatively fresh.
However, according to reports, under normal circumstances, the "top flower" of cucumber will wilt one day after the cucumber is picked, and when the cucumber reaches your hand, the "top flower" cannot still be delicate.
In addition, such cucumbers, the top of the cucumber and the "top flower" often grow an extra piece and have a bulge, which is enough to show that the cucumber is estrogen.
5.Water spinach. Because after the water spinach is planted in the ground, its most tender part is often picked, and the roots will continue to grow, this cycle is about 5-7 days, this process is very fast.
Due to its special growth cycle, the leaves on it are often picked, while the roots remain in the soil, resulting in the accumulation of roots.

1. Water spinach. Because water spinach is often repeatedly picked for the most tender part of its upper part, the roots remain in the soil, resulting in the accumulation of pesticides in the roots. In addition, for water spinach planted in summer, vegetable farmers will constantly apply pesticides to the leaves to prevent insect pests.
In this way, the two add up to make water spinach the first of pesticide residue vegetables."
2. Cucumbers. Many people buy cucumbers and think that the top flowers are "thorny" and relatively fresh. However, in general, the top flower of cucumber "wilts one day after the cucumber is picked."
If the top flower of the cucumber is still fresh and there is a raised part at the junction, then the split type is estrogen.
3. Cauliflower. Due to the shape and tenderness of the cauliflower, its appearance will be wrapped in a layer of paper or film during transportation. As a result, the pesticides on the cauliflower cannot be volatile. In addition, the surface of cauliflower is uneven and difficult to clean, so pesticides can easily remain in it.
4. Cabbage. Removing pesticide residues from cabbage does not mean throwing away the leaves from the outer skin. Because in the growth process of cabbage, at least two pesticides must be applied.
One is hit on the roots of cabbage to avoid maggots eating the roots, and the other pesticide needs to be hit on the leaves, which is to prevent normal insect pests. Moreover, according to the experiment, the amount of pesticide residues in the inner layer of cabbage is generally higher than that in the outer layer.
5. Tomatoes. At present, tomatoes are mostly cultivated in greenhouses, and their stamens cannot be pollinated normally, so tomatoes are usually grown by vegetable farmers with some growth regulators on the pistils. As a result of this cultivation method, tomatoes often have different shapes of deformity and hollowness.
If the color of the tomato is red on the outside and green on the inside, it is a ripening agent.
