Texas Rice: Endigo ZC Gets EPA Crisis Exemption to Control Planthopper

We obtained a Crisis Exemption from EPA for the use of Endigo ZC for control of the rice delphacid/planthopper attacking ratoon rice. 

The infestation of this exotic pest occurred late in our ratoon crop season. The preharvest interval for this insecticide is 21 days, so this Crisis Exemption expires November 9, 2018. Contact me (409-239-4265 or moway@aesrg.tamu.edu) if you want the document specifying all the details for use of this insecticide. In addition, contact me if you suspect this insect is infesting your rice.

You should apply Endigo ZC before hopperburn is observed in your field.

Hopperburn is caused by direct, excessive feeding of both nymphs and adults and results in off-color rice (yellow and/or dying foliage). Usually, you will see somewhat circular spots of dying or off-color rice scattered through the field. As time progresses, these spots increase in size. We hope to obtain a Section 18 Emergency Exemption for this same insecticide for both our main and ratoon crops next year. I will keep you posted on our progress. Many thanks to Dr. Pete Eure with Syngenta Crop Protection and Kevin Haack with TDA for providing extremely important assistance/information in obtaining this Crisis Exemption. I also thank Cliff Mock, Weldon Nansen, Casey Smith and Jason Supak for their help and cooperation.

On another note, back in September, we hosted the Ruben Stringer Memorial Texas Rice Education Contest. We had about 60 FFA members from 7 high schools compete for recognition and prizes which were handed out at the 49thAnnual Texas Rice Festival in Winnie on October 6, 2018. The top FFA chapter was Hamshire-Fannett and the high point individual was Amanda Duplechin (a senior at Hamshire-Fannett) who has won this coveted award 3 years in a row! If you want a copy of the test, contact me.

I would also like to congratulate Tyler Fitzgerald for being selected the 2018 Texas Rice Festival Honoree. Tyler and his family are long time rice farmers in Chambers County. Tyler recently accepted the position of Jefferson County Extension Agent (CEA). Prior to this position, Tyler was the Chambers County CEA. We wish Tyler and his family much success and happiness…
