Problems solved by technology

Seedlings and saplings are particularly severely damaged, resulting in fallen leaves and dead shoots, which will affect the tree vigor; the severely damaged fruit will drop fruit, and the light one will have disease scars, which will not tolerate storage and rot, which will greatly reduce the commodity value of the fruit and increase the cost of disease and pest control for fruit farmers. , loss of economic benefits
[0005] Zou Haiyong and Hu Linying disclosed the drug efficacy test of 20% copper acetate water dispersible granules in the prevention and treatment of citrus canker in "Southwest Gardening". However, the 20% copper acetate dilution alone needs to be sprayed several times. 10 days of supplementary application of medicines in sequence, 3 times in a row, the dosage is large and troublesome to use

Abstract

The invention provides a sterilizing composition containing copper acetate and amino-oligosaccharin. A mass ratio of the active ingredient copper acetate to the active ingredient amino-oligosaccharinis 10:(2-3), the copper acetate and the amino-oligosaccharin have synergistic effects in a certain combination ratio, and the composition has an obviously better pathogen prevention and treatment effect than the individually used active ingredients, achieves fast repairing after application, makes the back sides of ulcerous plaques become dry 1 d after being applied, acts obviously 2 d after beingapplied, makes the orange canker prevention and control rate reach 91% 4 d after being applied, and makes healthy leaves not continuously infected after being applied for 30 d. The composition has along persistent period, and has good adhesion and strong rain souring resistance when uniformly sprayed on the front sides and back sides of citrus leaves, and the EC50 value of the sterilizing composition can be as low as 1.308 [mu]g / mL.

Description

technical field [0001] The invention relates to the field of biopesticide sterilization and its application, in particular to a bactericidal composition containing copper acetate and amino oligosaccharin, which is applied to the prevention and treatment of citrus canker. Background technique [0002] Copper acetate, the molecular formula is Cu 2 (CH 3 COO) 4 It is a dark green monoclinic crystal with a melting point of 115°C, Cu monohydrate 2 (CH 3 COO) 4 (H 2 O) 2 Slightly blue-green, copper acetate was used as a fungicide and green pigment in ancient times, and also as a catalyst or oxidant in organic synthesis, paint quick-drying agent, pesticide additive, enamel pigment raw material, etc. Copper ions have a good control effect on common fungal and bacterial diseases, but general copper preparations cannot be used on sensitive crops, nor can they be mixed with foliar fertilizers containing metal ions, otherwise complexes will easily be produced and cause young shoo...
