Summer grass weed species are becoming more troublesome in orchards in the Central Valley of California. Feather fingergrass, junglerice, sprangletop and threespike goosegrass, to name a few, are summer grass weed species that germinate (or in some cases, resume growing) when the soil temperatures start to rise in the spring, develop during the summer and complete their life cycle in the fall. With such a life cycle, summer grass weed species reach their maximum biomass accumulation late summer/early fall – coincidently when harvest operations are taking place – if previous weed management approaches were inefficient. To make matters worse, some of the mentioned weed species have some degree of glyphosate...

March 16, 2016. Editor's note.
I recently was informed of an error in the chart Lynn included in this post from December 2018. While Broadworks (ai = mesotrione) herbicide IS registered in several stonefruit crops, it is NOT currently registered for use in peach. This was entirely my error.
I struck out inclusion of peach in the text below and replaced the chart with an updated version in this post. Remember to always read a current label before applying any pesticide as labels change (or can be misread as was...
