How much work does it take to get rid of a weed? Will I need to treat this population again next year? These are simple questions when managing weeds and the answer falls into a general pattern.
In general, a single treatment on annual weeds with short-lived seeds can be effective, and a treatment next year might not be necessary. In annual weeds with a longer-lived seed bank the treatments can be effective on current growth but not visibly effective the next year. For perennials single treatments can be very effective and they can be successful for many years. Proper identification is paramount and a knowledge of the biology of the weed also provides tremendous help with eradication measures, especially if you are pressed...

UC Cooperative Extension Farm Advisor David Doll is organizing a "Central San Joaquin Valley Summer Almond Field Day" on June 1, 2012. More info HERE or in the agenda at the bottom of this post.
As a part of a diverse almond research agenda that David has put together, we'll be discussing the results of several current herbicide efficacy experiments that my groups is conducting at this site as well as other locations in the state. The primary herbicide experiment that we'll discuss includes a number of residual herbicide comparisons including various rates and tank mixes of Alion, Pindar GT, Prowl, Trellis, Rely, Surflan,...

A quick repost this morning of a recent Weed Science Society of America (WSSA) press release about online databases and smartphone apps for tracking invasive weeds.
Technology that allows integration GPS coordinates and automated (or semi-automated) managment of huge, constantly changing datasets is evolving quickly. The ability for non-technical weed managers to use smartphones to monitor and even help map the location and movement of invasive weeds may allow new opportunities to identify invasions while they are small which can significantly increase the chances for successful eradiction or economical management. Pretty cool stuff!

Introduction
Weed seed are the means by which annual weeds reproduce and disperse. The seed buried in the soil is referred to as the seedbank. Most seed in the soil seedbank were produced in the same field or greenhouse. Some of the seed in the seedbank moved there through the actions of wind, water, animals or the activities of man. Annual weeds usually regenerate from seed stored in the soil seedbank. The seedbank reflects the effectiveness of recent weed management practices in the field or greenhouse and will determine future weed infestations. This article will outline some of the factors that influence weed seedbanks and how to use steam to kill weed seeds.
