面临挑战
The operator was applying fungicide every ten days yet Botrytis kept spreading. Resistance was building and input costs had climbed sharply.
解决方案
Rather than switching fungicide we first monitored the greenhouse climate. The data showed night-time relative humidity staying above 90% with VPD close to zero. Night ventilation, irrigation timing and plant spacing were revised, and fungicide use was cut to two preventive applications at critical points.
实施成效
Fungicide use fell 60% and infection was limited to scattered cases the following season. Fruit storage quality improved as well.
