When it comes to buying vegetables, modern consumers not only want them to look fresh and appetizing but also free from pests. To attract customers, some farmers resort to regular pesticide spraying during the cultivation process. While the vegetables may eventually make it to the market, they still contain pesticide residues. Therefore, when purchasing vegetables, we should try to avoid those that typically require the use of pesticides.
Today, I have specially categorized six types of vegetables that can be grown and harvested without the need for pesticide spraying. If you have elderly family members or young children at home, pay attention to these vegetable types to ensure their health and safety.
The First Type: Lettuce
Lettuce grows rapidly and is highly sensitive to pesticides. The bitterness of lettuce and the presence of erucic acid are two important factors that contribute to its distinct bitter taste and astringent property. Insects that take a bite will perceive these two substances as toxic, causing them to stay away from lettuce and other similar greens.
Lettuce is quick to grow and highly sensitive to pesticides.
The Second Type: Squash
Squash has a unique self-protection mechanism in the form of insect-repelling genes. These genes keep small insects at bay, making squash a remarkable crop that rarely falls prey to diseases. Squash is not only sweet but also rich in dietary fiber, making it an excellent choice for children’s breakfast.
The Third Type: Loofah
Loofah has a distinct odor that naturally repels small insects. Moreover, loofah is not easily attacked by pests, and it can even halt their growth.

The Fourth Type: Chrysanthemum Greens, Coriander, and Fennel
Coriander, chrysanthemum greens, and fennel are effective insect repellents due to their strong aromas. This makes insects reluctant to come near them. Generally, the number of insect pests is minimal, so pesticides are usually not necessary. Those who are cautious about pesticide use can rest assured when consuming these vegetables.
The Fifth Type: Lotus Root
Lotus root does not require pesticides because it grows in muddy water, which is inaccessible to insects. Therefore, lotus root is extremely safe and suitable for the elderly and children during the summer and autumn seasons.
The Sixth Type: Potatoes
During their growth cycle, potatoes do not need pesticides because they grow underground, making it difficult for pests to access them. Additionally, potato leaves are naturally coated with fine hair, creating a barrier that prevents pest intrusion, ensuring the safe growth of potatoes without the need for pesticides.
