Method for prevention, treatment and control of gummosis of peaches in field

Abstract

The invention discloses a method for the prevention, treatment and control of gummosis of peaches in a field. The method comprises the steps: (1) selecting peach trees with consistent tree body growth from an adult peach orchard, and scraping gum from gumming points with bamboo chips; (2) after scraping off the gum and marking, carrying out five treatments on the gum scraped points: 1, smearing a 150-times carbendazim solution; 2, smearing the 150-times carbendazim solution, and smearing tung oil after medicine liquid is naturally dried by air; 3, smearing the 150-times carbendazim solution, and smearing varnish after the medicine liquid is naturally dried by air; 4, smearing the tung oil; 5, smearing the varnish, wherein a reference treatment comprises the step of scraping off the gum without smearing any medicament, each treatment is carried out on 4-6 peach trees, and each peach tree has not less than 20 gum scraped points; (3) carrying out experiments that the treatment of gum scraping for one time and smearing different medicaments and protective agents is carried out respectively in a growing period and a dormancy period, and counting the re-gumming ratio of the gum scraped points, which are subjected to the five treatments in the growing and dormancy periods, in a next dormancy period. Shown by results, the best treatment comprises the steps of scraping off the gum and smearing tung oil in winter; the tung oil is low in price and is non-toxic, non-amyctic and pollution-free, and the field operation is simple, so that the popularization is facilitated.

Description

technical field [0001] The invention relates to the field of plant protection, and more particularly relates to a method for preventing and controlling peach gummosis in the field, which is suitable for field prevention and control of peach gummosis.
