Use of herbicides

Sir, — In response to “Herbicides reduced,” (“The Press,” August 20) I can say I have been informed that the New Zealand forest industry uses about 10 per cent of the total quantity of 2,4,5-T used here in a year. A survey conducted by the Forest Research Institute on use of herbicides in New Zealand forestry operations indicated that the Forest Service accounts for only 4 per cent of the total use of 2,4,5-T in New Zealand. The chemical 2,4,5-T does not have a big role in forestry at present except in the initial land clearing where broom is the dominant weed species. In this situation it is of vital importance. There are no alternatives to 2,4,5-T in forestry, particularly where gorse control is essential. Much of the country is too steep for the use of machinery. Mechanical techniques have not been successful and have been very costly. Hand clearing of certain brush weed species on densely infested sites is onerous and costly and has been ineffective. — Yours, etc..
