What medicine is used to treat wheat bacterial leaf streak?

Bacterial leaf streak of wheat is one of the main diseases of wheat. This year, it has occurred to varying degrees in major wheat producing areas such as Henan, Shandong, Hebei, Anhui, Hubei and other major provinces. So what medicine can be used to treat bacterial leaf streak of wheat? Let’s take a look below.

1. How to identify wheat bacterial leaf streak?

From the disease, you can easily identify "stripes" and "spots". The specific identification method is:

In the early stage of the disease, dark green spots the size of a needle tip appear on the wheat leaves, which then expand into translucent water-soaked streaks. In more serious cases, they will turn dark brown and develop granular bacterial pus.

2. Under what conditions is wheat bacterial leaf streak likely to occur?

1. The frequent rainfalls cause wounds on the leaves, which are then infected by bacteria many times, resulting in diseases.

2. The soil is fertile, the sowing amount is large, and the air permeability of wheat is poor;

3. Apply too much fertilizer and concentrate it. Too much nitrogen fertilizer will cause the plants to be densely packed, and poor air permeability and light transmittance are also likely to occur.

3. How to prevent and control wheat bacterial leaf streak?

1. Select disease-resistant wheat varieties, control the sowing amount and fertilizer application amount to achieve scientific sowing;

2. Seed treatment: Soak the seeds in 45℃ water for 3 hours, then mix with 0.01% Kunlunfeng brand brassinolide, dry and sow;

3. When the weather is cloudy and rainy, use Kunlunfeng + agricultural streptomycin sulfate for spraying in advance; or use 30% Kunlunfeng brand pyraclostrobin + Plant Challenge King + Kunlunfeng brand brassinolide for spraying;

4. Use 20% chlorothalonil + Kunlunfeng in the early stage of the disease; or 20% thiophanate-methyl + Kunlunfeng brand brassinolide for spraying; spray once every 7 days or so, for 2-3 times in a row.

That’s it
