How to prevent corn rough dwarf

Maize rough dwarf disease is a virus disease transmitted by the planthopper, which has been aggravated in recent years and has a serious impact on corn production.

1. Symptoms: The corn can be infected during the entire growth period, and it is the most affected during the seedling period. Symptoms can be seen in 5-6 leaves of corn, and the leaves are not easily extracted and become smaller, which can be used as a basis for early diagnosis. Beginning at the base of the heart leaf and at both sides of the midrib, a transparent oil-immersed green dotted line is created, gradually spreading over the entire leaf. The leaves of the diseased plant were short and stiff, with dark green leaves and thick internodes. The top leaves were clustered like a clivia. Leaf veins, leaf sheaths, and temporal lobes have waxy white sticks on the veins of the leaves, showing a noticeable roughness. In the 9-10 leaf stage, the dwarfing phenomenon of the diseased plants was even more pronounced. The upper internodes were shortened and swollen, and the top leaves were clustered. The diseased plants were less than half the height of the healthy plants, and most of them were not heading and fruiting. Although some tassels could be extracted, Very few branches, no pollen. Ears are misshapen, with few filaments, severe dwarfing of plants, degeneration of tassels, and abnormal ear formation.

2. The law of occurrence: corn rough dwarf disease spreads the virus with poisonous planthoppers. The nymphs or adults of Laodelphax striatellus were overwintered under the weeds on the ground and under the field seedlings, which was the source of infestation early in the year. The poisonous planthoppers in spring spread the virus to the turning green wheat and later spread it to the corn from wheat, weeds, etc. The occurrence of this disease depends to a large extent on the number of individuals and the number of individuals in the fields of SBPH. The incidence of early sown maize is heavier than that of late sowing maize, and the incidence of corn near the top of the ground, canals, and roadside weeds is heavy and near the vegetable fields. Wet, weedy, and more corn are also affected, and there is a certain degree of morbidity between different breeds.

Comprehensive prevention and control of corn rough dwarf disease: 1. Selection of resistant and resistant varieties. According to recent surveys, there are certain differences in disease occurrence among varieties. Nongda 108, Zhengdan 958, Ludan 981, and Ludan 984 have a relatively mild disease incidence, and the diseased plant rate is below 5%.

2. Agricultural control. Before weeding and before sowing of crops such as wheat and corn, remove the weeds at the edge of the field and the ditch, intensive cultivation, timely weeding to reduce the source of insects. Spray 40% omethoate EC 1500 times on corn field and surrounding weeds. Appropriate adjustment of the sowing date of corn so that the seedling period of corn misses the peak of the plant. Strengthen field management, improve plant resistance to disease, remove diseased plants in time, reduce diseased plants and sources of poisons, and severely change the early stage crops into legumes or sweet and waxy corn to increase economic income.

3. Chemical control. Including seedling control and panicle blast control. Medicinal planting of wheat aphid and silybinum can be controlled by spraying 10% imidacloprid 10 grams per mu; in the third and fourth leaf stages of corn, spraying control of planthoppers around the fields and plots can prevent and control the planthopper. The medicament can be used 40% omethoate emulsifiable concentrate or 5% fipronil suspension 30 ml or 10% imidacloprid 15 g, spray 30-40 kg of water; also can use 4.5% beta cypermethrin 30 ml or 48% chlorpyrifos 60-80 ml, Spray 30-40 kg on water. The sprayer strives to be even and thoughtful, and then controls it once every 7 days to ensure the control effect.
