IOA Wednesday, April 25, 2001 Environmental News m m By Victoria Metcalf Staff Writer Yellow starthistle (YST) is more than a nuisance, it's a hazard. The tall plant, noted for its small, bright yellow flowers and long thorns that catch and tear, is a danger to horses who eat it. It is also spells doom for any pastureland or field, once it sets root and starts to spread. The Plumas-Sierra County Agriculture Department has spent the last three years, and possibly longer, concentrating on ways to rid the two-county area of this noxious weed. Studying the problem, Agri- culture Commissioner Karl Bishop said there are two ways to fight YST. One is the use of special wee- vils raised in the state's agri- culture bug programs. These attack the plant at two levels, depending on which of the two weevils is introduced to a crop most effective ar/s er to the a fraction of the amount for of YST. area s problems, and'i what their use, Bishop explained.

Although the Plumas-Sierra County Agriculture Commis- sioner Karl Bishop has plans to bring in a Transline manu- facturer to answer public con- cerns at the May 15 Board of Supervisors' meeting, Bishop has offered a little early infor. mation. In a fact sheet written by DowElanco, Transline is hailed as one of the most effec- tive treatments ever devised for improving forage produc- tion in pastures and maintain- ing rights-of-way. By Victoda M .aif Staff Writer Environmental attorney Michael Jackson, of Quincy, threatened to sue the Plumas County Board of Supervisors, if he finds an approved use of the herbicide Transline is harmful. Jackson raised his objec- tions during an agenda item, giving the Plumas County Agriculture Commissioner permission to begin the second phase of an herbicide spraying campaign against yellow starthistle (YST). .Su- pervisors approved the pro- gram last year, allowing the department to spray county road edges with the state ap- proved herbicide Transline. On the consent agenda was a request for approval to begin the second phase of that pro- gram, which is supplying pri- vate landowners with a suffi- cient amount of Transline to allow them to spray their own property to eliminate the inva- sive noxious weed. Agriculture Commissioner Karl Bishop was requesting ap- It was developed to attack proval for four, 10-hour days the .toughest broadleaf weeds, for his snra, ino crews a ~~, ;~rtd..~tR~jl~:~~~said ~t the par Fthe plant ....... : tim 8tfi /esti- The active ingredient in Transline, clopyralid, is ab- sorbed by the leaves and stems and then spreads throughout the entire plant, including the roots and keeps them from re- sprouting. And when applied at the right time of year--now--it stops plants before they can produce seeds. One of the ma- jor problems with YST is that the plant can disappear, such as with hand pulling, but seeds left behind can remain dormant in the soil until it is disturbed, and then the crop returns. According to the DowElanco company, a single application is enough. Additionally, Transline contains a non- volatile active ingredient that stays where it's applied. California was originally targeted for sales by DowElan- co. The company thought "the product's roadside and non- crop designation limited po- tential sales to where they wouldn't justify the extra reg- istration expense." That changed and in 1997, the product was approved in California. A weed specialist with U.C.-Davis began testing Transline on YST. This not on- ly got the company's attention, but the state's as well. When looking at the active ingredient, clopryalid, label- ing in California does specify some limitations about where it can be applied. But DowE- lanco points out the same ac- tive ingredient that appears in Transline is in a registered range and pasture approved product called Reclaim, used heavily in Texas and Okla- homa for mesquite coi trol.

County Counsel Rob Shul- man told Bishop that he wasn't providing enough information on the topic, and that he need- ed to supply complete backup material about the herbicide. Bishop said he had provided that information to the county administrative officer (CAO). He pointed out that the board approved the program last year, and this was a routine re- quest for the second phase. Bishop explained that Transline, the most effective herbicide used in the fight against YST, was originally ap- proved at the national level 40 years ago. California, after fur- ther testing, only approved the herbicide for use, three years ago. Bishop said the herbicide is expensive. It sells for $300 a gallon, and is used in small quantities--just a few ounces mixed with water will cover acres. Because of this, it is cost prohibitive for most private landowners to purchase a gal- lon, when all they need is a few ounces, a pint or a quart, to cover their land. That's why, in the second phase of the program, interest- ed landowners have been trained and given written per- Get your Soil amendments add nutrients and Improve SOil texture, aeration and drainage.

All of the expenses for the project are covered by the state in funding generated through SB1740. As far as public comment was concerned, Bishop said he didn't know what else to do. He has helped promote the need to curb YST through features in the county newspapers over several years. And while he has heard comments that the stories were widely read, he said no one has voiced con- cerns about Transline's use. Bishop added that Plumas and Sierra counties are still fortunate in that YST hasn't spread to the extent it has reached in other counties in the state. Through applications of Transline, which eliminates only YST and doesn't harm other plants, residents are be- ing given the opportunity to help curb the problem before it starts destroying major sec- tions of land. (See sidebar on YST.) When some supervisors con- sidered tabling the item, Bish- op objected :' He said it'S important to spray now, or they have missed their window of oppor- tunity this year. If held up, Bishop said he would lose three weeks until the item could come up again before the board. Supervisor Robert Meacher, who was chairing the board in the absence of Don Clark, re- minded the board this is the second year of the project. He also said this is a state ap- proved product and has met with the state's stringent tests. Jackson said he would make the board a deal. He said he would not sue them this year, but he will next year if he learns that Transline is a harmful product. Bishop explained that, to date, county roads and Sierra counties are uing to be treated. National Forest has any spraying of cross through its land appropriate federal be conducted.
