sorghum and corn also plagued by cinch bugs

***Central Kansas farmers are being warned to scout for chinch bugs after reports of hefty numbers of the pest on corn and sorghum have surfaced in Lincoln and surrounding counties. While Kansas State Extension specialists say corn is more tolerable to chinch bug damage in later stages of development, younger sorghum plants offer prime food source for the insects.

Sandra Wick, Kansas State University crop production specialist, says with wheat harvest wrapping up, the pests are quickly moving out of harvested wheat fields and into adjacent corn and sorghum.

"All life stages of chinch bugs seem to be extremely active at the present time in both corn and grain sorghum. Nymphs and adults started migrating out of wheat fields at least two weeks ago, moving into any adjacent corn or grain sorghum fields. Those smaller-reddish nymphs have grown considerably since then, and are now late instar nymphs or adults," she said.***

wheres DDT now that we need it???

mono cultures even with rotation are not sustainable on large scale. We reduced biodiversity so only pests that can thrive on the grown produce will reproduce in large numbers. The bees have been killed off through secondary poisoning and overtaxed use and transport. Beneficial insects are killed with spraying indiscriminately.

Though I do not believe we could switch to smaller greener farms and still feed the country and beyond it does make rural better.

Mississippi sorghum plagued by aphids

“Economic issues will help or hurt sorghum, but the main cultural issue we’ve had is that the sugarcane aphid adapted and began using sorghum as a host,” said Erick Larson, Mississippi State University Extension Service grain agronomist. “This is causing a lot of heartache and reduced the profit potential for that crop substantially in our area.”

any local reports?
