The Treflan label now gives up to 4 hours for incorporation. Be sure you get Treflan on 

 the right fields --only on those to be planted to soybeans, not corn. Incorporate Treflan 

 twice- -once soon after application to reduce surface loss and again just before planting, 

 to give final seedbed preparation, control of broadleaved weeds, and a more-uniform dis- 

 tribution. 



If you want to use CIPC for added smartweed control, don't mix and incorporate it with 

 Treflan. Apply CIPC to the soil surface at, or soon after, planting. Use 2 to 3 pounds 

 per acre of active CIPC on a broadcast basis, either as liquid or granules. Apply pro- 

 portionately less in a band. 



NEW CLEARANCES 



Lasso plus atrazine tank mix has been approved for corn. When used for preplant applica- 

 tion, incorporate it like you would Lasso alone. There will probably be greater interest 

 in surface applications at planting, since these provide broad -spectrum control of annual 

 grasses and broadleaves. Use about 1-1/2 quarts Lasso plus 1-1/2 pounds atrazine 80W 

 (broadcast basis) on light-colored silt loams with less than 3-percent organic matter. 

 Use about 2 quarts Lasso and 2 pounds of atrazine 80W per acre for the darker, clay soils 

 with over 3 -percent organic matter. 



Where Ramrod plus atrazine has performed well, growers should not be in too big a rush to 

 switch to Lasso-atrazine, especially on the darker soils. However, the Lasso-atrazine 

 combination would be less irritating to handle and better adapted to the light -colored, 

 silt loam soils than Ramrod/ atrazine. Because Lasso is available as a liquid, the amount 

 of water required per acre may be less than with the Ramrod- atrazine wettable powder. 



Lasso plus Lorox is also cleared as a tank mix for soybeans . This combination has per- 

 formed well in research trials, especially on the light-colored silt loams. Adjust rates 

 on the basis of the organic -matter content. The Lasso-Lorox combination should be applied 

 only to the surface and not incorporated. 



AQUATIC WEEDS 



It is not too early to consider a program of aquatic plant control. Frequently, people 

 wait until this problem is serious then wonder what happened. Actually, the problem has 

 been developing and growing slowly since mid-April or earlier. When the warm weather 

 comes, the water warms up rather quickly. Soon after, the weed infestation becomes severe. 



Consider what has happened during the past few years . Take time to check the body of water 

 frequently, to see if some aquatic plant is growing. If it is, identify the problem and 

 obtain the necessary aquatic herbicide so you will be ready when necessary. If a particular 

 body of water was weedy last year, it is reasonable to expect that it will be again this 

 year. 



HOMEOWNER PROBLEMS 



Now is the time to apply herbicides for crabgrass control in the lawn. Many excellent 

 chemicals have been put on the market recently for preemergence control of crabgrass and 

 certain other annual grasses. These materials may also control certain broadleaved weeds.
