BEST TIME TO CONTROL RAGWORT WITH HORMONES
(Contributed by E. R. Marryatt, Fields Instructor,- Department of Agriculture, Whakatane) Recent enquiries about hormone treatment of ragwort show that a note about the present knowledge of the subject will be of value. The position is that control of ragwort by hormone-type weedkillers is not as successful as is control of buttercup and pennyroyal by these growth-inhibiting chemicals but when the applications are made at the correct time and in the proper way results are good. January - February application gives the best control of ragwort with hormones. The treatment should, in general, be applied just before the plant flowers. This will not give 100 per cent kill and spot treatment is essential in subsequent years. Sprays seem to give better results than dusts but oil-based sprays do not necessarily give better results than the water-based. Control by sodium chlorate can be applied at any time but application of hormones to ragwort should be confined to January-February.'
