I'm going to spray my wheat crop with 2-4 D, but the plant has just started to form spikes. Are there any risks? What are they?
Yes, spraying 2,4-D during the ear formation stage of wheat is dangerous and can cause significant crop damage. Here are the main risks:
1. Ear deformity
2,4-D is a hormonal pesticide that affects cell division and growth. If sprayed during or just before the flowering stage (ear formation), it can lead to:
• Ear deformity.
• Reduced grain count per ear.
