Remedial measures should be taken as soon as possible.
When wheat grows and develops to winter and spring, wheat seedlings often appear yellowing or even withering, but wheat can not turn green by single fertilization. Once the yellowing of wheat occurs, if no timely measures are taken to remedy it, the yield of wheat may be seriously reduced. Pest yellowing: wheat aphids and wheat spiders cause leaf yellowing caused by leaf juice, which mainly occurs before and after overwintering. For every 667 square meters, 50 kg of water can be sprayed with 40% omethoate EC 65-75 ml.
