Wheat bush dwarf disease, also known as slope-slip disease, is a devastating disease that has frequently occurred in recent years. It is mainly transmitted by the poisonous planthopper that sucks leaf juice. The rate of illness increases with the prolonged smoking time, and it can be poisoned once it is acquired. Overwintering with poisonous nymphs in the rhizosphere of the weeds or earth seams overwintering, year after year back to spring seedlings harm. Most of the pre-winter diseased plants could not die through winter, and the lightly diseased plants grew thin after turning green. The plants were dwarfed, and the leaves had yellow-green stripes. Generally, they could not be jointed and headed. In the early spring, the susceptible plants showed symptoms in the turning green and jointing stage. The leaves were slightly dark green, and the upper leaves were stripped. Most of them could not head, or the heads were small, and the grains were thin, posing a great threat to wheat production.
In the past, the disease had been interplanted in intercropping between cotton and wheat. As the area of ​​cotton and the intercropping of wheat decreased, in recent years diseases occurred near the edge of wheat fields near cotton fields, vegetable fields, orchards, and spring and white fields. And once the disease occurs, it spreads inwards, and some of them push forward 3-5 meters or even the entire plot.
According to the living habits of Laodelphax striatellus in uploading and infecting wheat, it is necessary to seize two key drug-use phases: first, after the emergence of wheat, that is, two leaves and one heart, and second, when wheat starts to turn green after the year. To seize the critical period when the planthoppers began to feed on the wheat seedlings, the following methods were selected for spraying: First, use 5% cyhalothrin 1200 times and 50% phoxim 1200 times. The second is to use 70% imidacloprid water dispersible granules 3000 times or 50% thiamethoxam water dispersible granules 3000 times, while also controlling aphids, wheat spiders, wheat leaf bees and so on.
If it has been severely affected, on the basis of the above medications, add aminophenol hydroxy hydroxybenzoate 750 times and virus-free foliar fertilizer potassium gold, Eurasian, etc., in addition to the treatment of viral diseases, spray 1-2 times, interval 7-10 days. .
