No-tillers need to pay attention to the extra phosphorus, zinc and other nutrients that corn rootworm-resistant (CRW) hybrids use compared to biotech hybrids without the CRW trait, says Fred Below, University of Illinois plant physiologist.

No-tillers will be able to buy corn, soybean, wheat and field-bean seeds based on seed counts starting Jan. 1 after the National Conference on Weights and Measures recently approved standardized testing methods and procedures to verify seed count labeling.

The first confirmed case of weeds resistant to HPPD-inhibiting herbicides has been found in waterhemp in Illinois, according to University of Illinois weed scientists.

To no-tillers, atrazine, nitrogen and phosphate are indispensable for maximizing yields of corn, soybeans, wheat and other crops.
