Wheat drought conditions will worsen further; experts advise watering as soon as possible
In the second half of this month, our province will remain dry with little rain, and relevant experts advise promptly irrigating wheat fields in drought-affected areas to minimize the reduction in the summer grain harvest. In early May, temperatures in most parts of our province were on the high side, and precipitation continued to be below normal. Varying degrees of drought disaster occurred in Linzhou, Puyang, Lushi, Luanchuan, Yichuan, Xuchang, Xiangcheng, Shangqiu and other places, and soil moisture was lost relatively quickly, which had a certain adverse impact on the grain filling of winter wheat and the sowing of spring-sown crops and seedling growth.

Yellowing from pests: yellowing of leaves caused by wheat aphids and wheat spiders sucking leaf sap, mainly occurring around the overwintering period. For every 667 sq m, 65-75 ml of 40% omethoate emulsifiable concentrate can be mixed with 50 kg of water for spray control.

When subjected to weed damage at the seedling stage, plants appear short, with thin stalks and yellow leaves, which also aggravates the occurrence and damage of diseases and pests in corn fields,...
