Wheat field management measures in March

As March approaches, wheat in many planting areas has entered the jointing stage. Many farmers have managed the wheat by watering and applying fertilizer to promote the rapid greening of wheat. Let’s talk about the field management measures for wheat in March.

1. Weeding

The time is during the greening period of wheat - the rising period, and it is strictly forbidden to use pesticides after jointing. When using pesticides, choose appropriate herbicides according to the local weed species and strictly follow the instructions for use. Do not miss any spots or overspray, and do not pour the remaining pesticide liquid on the farmland.

2. Watering and fertilizing

After wheat enters the jointing stage, it is also a critical period for water and fertilizer needs. Therefore, if drought occurs in the field, the wheat turns yellow, and the growth is weak, attention should be paid to irrigation, watering, and topdressing. Especially when the local soil cracks and there has been no effective rainfall for a long time, water should be replenished and irrigation should be carried out in time. Some farmers may ask, if water has been applied during the greening period, is it necessary to apply water during the jointing period? Whether to water or not depends on the soil moisture conditions in the field. If the soil is still relatively dry during the jointing stage after watering, then watering is needed again. The same applies to topdressing. If urea has been applied during the greening period, but the amount is not much, and the growth of wheat is not ideal after entering the jointing stage, then topdressing is needed again. In short, whether wheat needs to be fertilized and watered during the jointing stage depends on the specific wheat in different plots.

3. Disease prevention and control

After wheat enters the jointing stage, diseases in the field begin to spread, such as stripe rust and sheath blight. Therefore, farmers should take corresponding control and prevention measures (mainly through chemical control methods). For stripe rust, commonly used agents include 250 g/L tebuconazole emulsion 30 ml/mu, 30% fluphenazine suspension 20-25 ml/mu, 12.5% ​​diniconazole wettable powder 30-50 g/mu, 250 g/L propiconazole emulsifiable concentrate 33 ml/mu, 25% triadimefon wettable powder 50-60 g/mu, etc.; commonly used agents for sheath blight include 12.5% ​​diniconazole wettable powder, 15-20 ml per mu, 250 g/L propiconazole emulsifiable concentrate, 45-60 g per mu, 10% hexaconazole suspension, 30-40 ml per mu, jinggangmycin, etc. Depending on the prevention and control situation, multiple sprayings can be made at intervals of 7-10 days.

4. Pest control

After wheat enters the jointing stage, the main insect pests are red spider mites, aphids, etc. These two pests are difficult to control and cause great harm due to their high density, small size, and easy occurrence on the back. For aphids, commonly used control agents include 5% acetamiprid emulsifiable concentrate 30-40 ml/mu, 70% imidacloprid water-dispersible granules 2-4 g/mu, 5% highly effective chlorfenapyr emulsifiable concentrate 10-14 ml/mu, 25% thiamethoxam water-dispersible granules 8-10 g/mu, 25% pymetrozine wettable powder 16-20 g/mu, etc.; for wheat red spider mites, commonly used agents include cypermethrin, abamectin, cypermethrin, chlorpyrifos, etc.

5. Pay attention to late spring cold

After late March, although the temperature gradually rises, we still need to guard against the occurrence of late spring cold snaps. We must do a good job of preventing late spring cold snaps. Commonly used methods include watering, fertilizing, spraying foliar fertilizers , and preventing and controlling diseases and pests. The purpose is to promote normal growth of wheat and improve its own resistance.
