What medicine does corn dwarf disease use to prevent and cure?

During the growth of corn, there will be striped dwarf disease, which will shorten the internodes and appear yellowish stripes on leaf veins, which will lead to plant death in the later stage. What medicine will be used for corn dwarf disease?

What medicine does corn dwarf disease use?

Corn dwarf disease can be controlled by imidacloprid, paracetamol, monocrotophos and so on. Generally in mid-June or winter irrigation, 10% imidacloprid wettable powder 3000-5000 times liquid, or 20% chlorpromazine wettable powder 1000-1500 times liquid, or 40% monocrotophos EC 1000 times liquid, evenly sprayed.

Second, how to prevent and cure corn dwarf disease?

1. Seed selection:

Disease-resistant varieties such as Qunzhuang101,Jinghuang113,Yunong704, 2569 × Huobai, Xidan 7, Zhongdan 2, Zhongdan 4, Nongdan 5 and Zhengdan 4 were selected.

2. Before sowing:

(1) clear the garden: remove weeds in the field and around, concentrate on burning or retting fertilizer; turn the ground deep to kill stubble, promote the decomposition of disease and residue, and reduce pathogens and pathogens.

(2) do a good job in field management: select fields with convenient drainage and irrigation, open drainage ditches, lower the groundwater level, so that there is no stagnant water in the rain; clean up the gully system in time after heavy rain to prevent moisture retention and reduce field humidity, which is an important measure to prevent disease. Promote continuous planting, avoid large-scale planting of single disease-resistant varieties, and achieve basically the same sowing date. In order to avoid the transmission of gray planthopper due to flower arrangement and a small number of corn fields, the susceptible growth period coincided with the epidemic period of gray planthopper.

3. Growth period:

(1) fertilization: apply compost made by enzyme bacteria or rotten organic fertilizer without bacteria-carrying fertilizer, and the organic fertilizer should not contain barley disease residue; adopt formula fertilization technology, properly increase phosphorus and potassium fertilizer, strengthen field management, cultivate strong seedlings and enhance plant disease resistance, which is helpful to reduce the disease.

(2) Insecticidal: timely and thorough removal or spraying of host weeds when they are unearthed is one of the key measures for disease prevention.

Timely spraying insecticide and germicidal agents to control aphids, gray planthoppers and other pests, cut off the pathways of pest transmission and bacteria transmission, and prevent germs and viruses from entering the wounds injured by pests and harming plants.

(3) Irrigation: water should be irrigated at high temperature and drought in order to increase field humidity, reduce the harm of aphids and gray planthopper and spread virus. Continuous irrigation and flood irrigation are strictly prohibited.
