Control method for corylus heterophylla fisch dodder

Abstract

The invention provides a control method for corylus heterophylla fisch dodder. The control method comprises the following steps that (1) the land outside corylus heterophylla fisch are ploughed depth in autumn, and the ploughing depth ranges from 5 cm to 8 cm, and dodder and the severely damaged portions of the corylus heterophylla fisch are removed manually; (2) thinning or intermediate felling is conducted on a corylus heterophylla fisch clump which is too dense so that the ventilation condition can be improved; (3) from April to late May, 200-fold to 400-fold 48% dibutalin (butralin) emulsifiable concentrate is sprayed three times; (4) from late May to mid June, a mixture of 40-fold to 600-fold 10% glyphosate and (0.3%-0.5%) ammonium sulfate and a mixture of 1.5% gyphosate solution and (0.3%-0.5%) ammonium sulfate are sprayed; (5) during each stage before July, a Zhenfeng Number three agent (the main ingredient is plant ash) is applied or a mixture of 1.5% sodium pentachlorophenate and 400-fold to 600-fold 2% prometryn liquid is applied. By the adoption of the control method, the quality of corylus heterophylla fisch products can be greatly improved; the method has the advantages of being efficient, safe, economical and the like.
