The Harm of Vegetables and Control Measures

Recently, readers of Mr. Wang of Leiyang City, Mr. Lin of Xihua County, and Mr. Zhao of Baofeng County dialed the newspaper's hotline number 110 for advice on how to control food dishes. The reporter interviewed the relevant experts of this newspaper's expert advisory panel on this issue. Experts pointed out that vegetables, commonly known as Cai Xin Ye, carrots, and borers. The main hazards are cabbage, radish, Chinese cabbage, cabbage, cauliflower, turnip and other cruciferous vegetables. The distribution of various vegetable areas in China is common and is a major pest commonly occurring in coastal provinces and northern China. The rapeseed meal is also an important medium for the propagation of soft rot in cruciferous vegetables.

First, the harm

Lepidoptera is a member of the genus Lepidoptera, which occurs in different generations throughout the year. The Yangtze River basin has 6-7 generations, 7-9 generations in the south, and 3-4 generations in North China. The larvae are larvae that spine in the soil and attach to the soil particles, withered off the fallen leaves, and make the braided silk sac overwintering (a few are overwintering). In the spring of the following winter, the wintering larvae do pupa in 6 to 10 cm of soil, and there are also phlegm on the dead leaves on the ground.

Adults are out of action and their phototaxis to the black light is weak. Every year, from late May to early June, eggs are spawned on the leaves and stalks of young plants, with the largest number of leaves on the heart. The average number of eggs per female is about 200, and the breeding coefficient is very high. After hatching, most of the larvae dipped into the leaf surface to feed on the leaf; at the second age, they also drilled leaves and moved on the leaf; after the third instar, they drilled into the cabbage, and the silkworms tangled the heart, hiding them, and eating food. Leaves; old larvae invade stalk and marrow. 9 to 40 days of larval stage, mature larvae are mostly in the soil surface or cracks near the vegetable root, a few in the hearts of the stricken cabbage, silkworms, pods and phlegm, pre-pupa period of 1 to 2 days, puerperal period of 5 to 10 days.

The suitable temperature for the growth and development of the vegetable larvae ranges from 15°C to 38°C. The optimum environment temperature is 26°C to 35°C, and the relative humidity is maintained at 40% to 70%. In the autumn, the year of drought and drought is generally heavy, and the cabbage and radish sown from August to September in the middle and lower reaches of the Yangtze River are heavier.

Vegetable worms are a kind of borer pests that endanger the heart leaves and leaves of vegetable seedlings, causing wilting or death and ridges and ridges. After cabbage and cabbage are damaged, they cannot be balled or wrapped.

Second, prevention and control measures

(a) clean the pastoral. Timely plowing can eliminate some of the overwhelming insect sources.

(b) Agricultural control. In autumn dry years, the sowing date should be appropriately adjusted so that the crops with 3 to 5 true leaves will be staggered in the flood season, and water and other facilities will be used for watering, increasing the humidity in the field, creating an ecological environment conducive to the growth of the seedlings and unfavorable to the growth and development of pests. Inhibit the occurrence and harm of pests.

(c) Chemical control. Should be mastered in the larvae at the beginning of the hatching period, when the seedlings first saw the damage of the heart, the spraying parts should be sprayed on the heart and leaves of vegetables as much as possible, and the interval between control and prevention should be 7-10 days, and the continuous spraying should be controlled 1-3 times, and pay attention to the alternate use of medicines. . The available pesticides include 2.5% Kung Fu Chrysanthemum Jujube 3000 times liquid (30-35 mu dose), 5% Calcined EC 2000~2500 times liquid (40-50 g mu dose), 5% Ferguson EC 2000 ~ 2500 times liquid (mu dosage 40 ~ 50 grams), 5% Citalop EC 2000 ~ 2500 times liquid (mu dose 40 ~ 50 g), 48% Loester EC 2500 times liquid (mu dosage 30 g) and so on.
