Abstract:
Taking tomato as material,the inhibition effect of bamboo vinegar reunited copper，compound amino acid cheated copper，cheated copper A and cheated copper B on bacterial soft rot of tomato were studied indoors and in the greenhouse.The results showed that the inhibition were strengthened with the increase of the concentrations by all copper treatments above，and the bacteriostasis of bamboo vinegar reunited copper was the best,with EC50 value 1.50 mmol/L.Therapeutic efficiency of bamboo vinegar reunited copper was 58.63% on bacterial soft rot of tomato in the greenhouse at the concentration of 2.50 mmol/L，which was significantly higher than the other copper preparations，while its preventative efficiency was up to 77.72%.
