A few years ago it became apparent from conversations and emails that the use of Fusilade (fluazifop-P-butyl, manufactured by Syngenta Crop Protection), a herbicide that only kills grasses (Poaceae), was increasing among wildland weed warriors. It's a very useful herbicide and can play an important role in natural habitat restoration.
But was this use consistent with the label? Was it legal?
Well, not really. There are two Fusilade products on the market, Fusilade II and Fusilade DX. The Fusilade II label says right on the top of the label that it is, “For the...

I'm sure you've noticed that different years have dominant weed species. For example this year in Southern California Russian thistle (aka tumbleweed Salsola tragus among other Salsola species) is abundant in many areas. Other years it is only moderately abundant and some years it seems to hardly hang on. The obvious question is why? Why is there so much variation in abundance between years?
Fortunately for us people have been working on this issue for a while and have a few general answers for us. Since the bulk of weeds in California are annuals I'll limit my discussion to those plants.
The seeds of annuals germinate only under a certain range of environmental conditions....

Preemergence herbicides for wildland weed control
Kill weeds before they ever see the light of day; sounds great, doesn't it? That is what preemergence herbicides are for. They are a mainstay in commercial agriculture and ornamental landscapes, so why not in wildlands? While there are situations where they would be very helpful I have some concerns that make me reluctant to recommend them in general.
First of all, what is a preemergent herbicide? (The shorthand version is PREE, so I'll use that term for the rest of this blog.) These are...
