Abstract
During the past few years growers have shown considerable interest in herbicide spraying for weed and grass control in both new and fully established fruit plantations. Materials at present available include the contract herbicides such as paraquat and diquat, those absorbed bed and translocated in the weed plant such as dalapon and aminotriazole, and the residual materials such as simazine, diuron and atrazine. These are normally applied in volumes of 80-100 gallons of water per acre of the sprayed area. The spraying method used varies according to particular conditions but, apart from ham! Lance treatment, three methods would appear to cover most requirements. These me the spraying of land between the rows, the spraying of a strip or close to the row and the spraying of areas at the bases of widc1y spreading trees. The first two methods have been med at Long Ashton and the simple equipment used is described here. A boom for tree-base spraying is under development.
