Armyworm returns in 2017

Armyworm returns in 2017

Armyworm has returned to rice fields earlier than normal this year. The Intrepid section 18 emergency exemption has been submitted for approval. However, we currently do not have a date when it will be available – or if it will be offered. The yield damage data we received to support the significant economic loss was minimal. Without the necessary data, we crafted an argument we anticipate will adequately justify the section 18. In the interim, the alternative insecticides are an option when the worm reaches treatment threshold levels.

Luis Espino, UCCE Farm Advisor, provides armyworm updates on the UC Rice Blog and on the UC Rice online website.

Information on field monitoring for determining treatment threshold level is found in the UC IPM Guidelines.

Please refer to the list of alternative insecticides with information on restrictions.

We will keep you posted on the status of the section 18.
