A cutting guide is provided, comprising a first clamping member having a first surface adapted to contact a pipe; a second clamping member having a second surface adapted to contact the pipe; a connecting device operatively disposed between the first clamping member and the second clamping member for connecting and urging the first and second clamping members toward one another to grip the pipe; and a cutting guide member, preferably a cylindrical member, attached to the second clamping member for slidably retaining and guiding a flexible cutting member in contact with the pipe. The first and second surfaces which contact the pipe are preferably contoured to approximate the shape of the pipe. Also preferably, the bottom surfaces of both the first and second clamping members are coplanar during operation of the cutting guide. Optionally, a recess is formed into the first clamping member which is adapted to receive a reducing member for contacting smaller sizes of pipe.

The subject invention relates to herbicidal compositions comprising a dinitroaniline compound and a freezing point depressant compound selected from the group consisting of butyrolactone, N,N-dimethylformamide, and mixtures thereof. The compositions described herein are used as preemergent herbicides and are particularly useful in the control of grasses and broad-leaf weeds for crops such as cotton, soy beans, and peanuts. The freezing point of the dinitroaniline compound is lowered by the addition of the freezing point depressant additive without having a detrimental effect on the activity of the dinitroaniline, the crop, or the environment.
