herbicide use in pine plantations
Applying chemical herbicides is an effective and sometimes necessary means of controlling unwanted competing vegetation from planted pines. Use of herbicides for pine release normally occurs when pine seedlings are 1, 2, or 3 years old. Chemical control (release) operations are normally conducted during the summer and early fall using âselectiveâ materials that will suppress competing brush, but have little or no adverse effects on planted pines.
