Speaking of arugula, the small partners living in the north should be no stranger, it is one of the wild vegetables (can also be artificially planted), people pick wild arugula to eat is not strange, and like the southern side of the country vegetable life is not seen there, when I bought vegetable seeds online, saw arugula seeds sold, think the name is very interesting to click in to see, thinking that this arugula have wild, strong vitality, should be good to plant and grow, just try to buy a small bag of seeds back to sow; after sowing, I found that this dish is not good to grow It is said that other wild vegetables such as houttuynia, fungus, wild amaranth, a little red, mugwort, plantain, etc. have been planted (I or my family planted), good planting and growth, by the insects are very few or not, can be ignored, but to arugula, but the opposite, the insects are obvious; I don't know if the small partners in the north have this feeling?
First, the sprouts of arugula are jumped
The sown arugula has broken through the soil for a week or so, but it is also with the emergence of seedlings, the pest will follow, it is really heart-wrenching; the pest that bites the arugula is the jumping nail, and the jumping nail of the cruciferous vegetables such as the cabbage in other articles is the same kind of pest, and after our side began to cool down on the 6th, the temperature is relatively low, the wind is strong, the cold is cold, there is no jumping nail, no photo, the wormhole on the leaf is bitten when the weather on our side is not so cold before.

Although the jumping nail is only biting the true leaf and cotyledon leaf surface of the arugula, it does not bite the main stem, but the impact on the growth of arugula that has only just emerged is quite large, because the presence of leaves can absorb and use water nutrient light to promote the growth of arugula, the pest bites the hole, the delivery route is blocked to a certain extent, the growth becomes slower, plus the weather is cold, less than 10 degrees, the growth is even slower; can only wait, usually pay attention to watering moist, long true leaves and then obvious points on the fertilizer, the plant is strong, the resistance to pests is also stronger, The follow-up should grow well, like the cabbage is also jumped after the emergence of seedlings, and the back can also grow up to eat.
The jumping armor of the arugula is the same as the jumping armor on the cabbage
Second, arugula is a cruciferous vegetable, easy to be insectized, not surprising
So why is it that wild vegetables, arugula, are easy to be insectized after being artificially planted? The small vegetables of the countryside suddenly remembered a small passage that people often say: "Dragons give birth to dragons, phoenixes give birth to phoenixes, and the sons of rats will punch holes", saying that the blunt point is the genetic influence or the influence of the original family behavior, and arugula is easy to be insectized, and it has to be mentioned that arugula is a cruciferous vegetable.
Usually people grow vegetables, cruciferous vegetables are more obvious, and the reason why cruciferous vegetables are easy to be insectized is because the special substances contained in this family of plants themselves are more attractive to pests, just like Asteraceae vegetables are not easy to be insects, and the plants of the Asteraceae family itself are also affected by special substances; when sowing arugula, the village vegetable field is planted with cruciferous vegetables such as cabbage and radish seedlings, and there are jumping nails in the field to harm cruciferous vegetables, and the sprouts of arugula are easy to suffer. After all, there are new vegetables that pests love to eat, and they do not refuse, just like us, the usual diet is also diverse, and each meal eats several kinds.
Arugula leaves
Jumping nails should be prevented
Jumping beetle pests harm vegetables, as long as there are vegetables they like to eat in the field, they will not go, want to better control this pest, generally to use medicine, which is good, with which kind of collocation wheel, it is recommended to consult the staff of the agricultural material store, this side of the rural farmers have people to the cruciferous vegetables spray predators and other broad-spectrum insecticides to prevent jumping nails, the effect is general, follow-up or easy to be jumped nails, also did not see them change other medicine spray, spray 2 times so that it does not spray; and like spray vinegar water, Simple soil methods such as scattering grass and wood ash have a short-term nature, and they have to be done many times, a little troublesome, depending on personal choice.
Arugula true leaves also have wormholes
Summary: artificially planted wild vegetables are not necessarily less insects, good growth, look at the types of wild vegetables, like arugula is the kind that is easy to be insectized, and other no comparison, that can only blame it belongs to the cruciferous plants, haha; of course, jokes are joked, since planted, insects or to control, otherwise affect the growth of arugula and follow-up picking, do not use drugs to control, in addition to fertilization and other strong plants, you can also choose some soil methods to control, but also a little effect.
