Wheat ear stage is a crucial period for the occurrence of various pests and diseases, making it a vital time for effective prevention and control. During this phase, common diseases include leaf blight, rust, powdery mildew, and head blight, while major insect pests consist of wheat midge, armyworm, aphids, and wheat leaf beetles. The primary method of managing these issues involves chemical control, but it's important to follow specific guidelines to reduce pesticide use frequency and minimize environmental impact.
In addition to chemical treatments, it's essential to protect and utilize natural predators to enhance biological control. This integrated approach helps manage pest populations more sustainably and keeps damage within economically acceptable limits, ensuring a successful wheat harvest.
**First, understanding control thresholds and timing of interventions**
For powdery mildew, intervention is needed when the infection rate reaches 10%. For leaf rust, treatment should begin when the infected leaf rate is between 5% and 10%. Stem rust requires action when the infected stem rate is 1–5%. Fusarium head blight should be addressed during the early flowering stage of wheat.
Regarding insect pests: wheat midge becomes a concern when 2–3 adults are found per infested spike; aphid populations should be monitored, with 500 individuals per 100 spikes as a threshold. Armyworms require attention when there are three third-instar larvae per square meter, and wheat leaf beetles should be controlled if up to 60 larvae are found per square meter.
**Second, recommended control measures**
To manage powdery mildew and rust, apply 20% tebuconazole EC at a rate of 1 liter per mu, or 15% triadimefon at 75 grams per mu, mixed with 50–70 kg of water. For Fusarium head blight, use 40% carbendazim suspension at 100 grams per acre, diluted in 60 kg of water. These treatments can also be combined with other disease management practices for better overall control. It’s important to monitor fields regularly and act promptly to prevent widespread damage.
