Sugarcane Aphids!

**Johnny Reb** · 07-06-2017, 01:03 PM

Lots of them! They are destroying my Sorghum/Egyptian Wheat road screen. This morning I was riding around looking at the fields and noticed the EW didn't look to good...starting to turn yellow, brown, and wilt over. It was about head high, green, and looked great up until this weekend. When I pulled up to it I noticed the leaves looked wet and thousands of wasps and lady bugs flying around the stand. I started examining the leaves and found the aphids on the underside.

I've been doing some online research but wanted to see if anyone can offer some control recommendations? 50% of my crop is infested at this point so it might be total loss if not handled immediately.

Lice?

Several pesticides out there to control them, most are not cheap.

Sivanto and Transform are your best bets in Grain Sorghum but are fairly expensive. Avoid pyrethroids as they tend to flare them and kill off the natural enemies.

Anyway to prevent them in the future or can you only treat for them once present?

This is presentation I sat in last year, fairly educational from Buntin.

Not likely to prevent them all together but use tolerant varieties, plant earlier, and use seed treatments.

Thanks guys. Great info!

They destroyed my entire crop since I started this thread.

I told Mr. Luther at Wannamaker about it and he said he had never heard of them eating/killing EW before.

I reckon will be planting something besides Egyptian Wheat for a road screen in the future.
