Topic of discussion: Will citrus pruning and scissors spread disease when picking?

Fear that scissors can spread citrus disease

Growers: There are about 20 suspected yellow dragon disease trees per acre, which will be picked after a period of time, cut the diseased trees and continue to cut healthy trees, worried about whether the scissors will spread yellow dragon disease. I also know that it is difficult to prevent and control now, and I only hope that the slow spread can be insisted on for one or two more years, do you think the scissors will spread?

Xiao Lu: I am not professional, I have not read the relevant information introduction, and it is rare to talk about this topic on the Internet, so I can't answer your question.

Growers: A small number of people think it will spread, and most people think it will not spread. In the past, cautious growers were seen to disinfect the scissors of the picking team uniformly before picking.

Xiao Lu: If you are worried about this problem, the day before the picking, please ask someone to pick the fruit of the suspected Yellow Dragon Disease tree, sterilize the scissors after picking, and then cut down the diseased tree to disinfect the tools. When picking normal fruit trees, the scissors of the picking team are uniformly disinfected.

Do scissors spread disease?

Citrus yellowing is increasing year by year, and some of the yellowing trees are yellow dragon disease, decay disease, and leaf fragmentation disease, which are currently incurable. On the question of whether scissors will spread diseases, Xiao Lu consulted professional technical teachers and folk planting teachers.

Teacher He: Scissors do not transmit yellow dragon disease, but they do transmit decay disease.

Teacher Ou: This scientific research department has proved that scissors do not transmit yellow dragon disease. However, it will spread other diseases, more than ten known viral diseases, and chlamydia and the like!

Mr. Liu: I think scissors should not spread yellow dragon disease, if they will, there will be fewer good orchards, I am also here with scissors (not sterilized) picked, I don't know how many fruit trees have been cut.

Mr. Shi: At present, many teachers and experts say that scissors do not spread yellow dragon disease. I think the scissors and saws when pruning are the most terrible, scissors and saws leave a lot of juice after pruning, and there are not so many scissors picked.

Summary: Most people in the citrus industry believe that pruning and picking scissors will not spread yellow dragon disease, but it will spread other diseases, such as recession disease, leaf fragmentation, etc., and the disinfection of picking and pruning tools is necessary. In theory, one tree is cut and one disinfected, but in reality, it is difficult to implement this, almost impossible.

Diseased trees can be picked uniformly, and the scissors will be disinfected after picking, and the diseased trees that need to be cut down will be disinfected by cutting tools. The scissors brought by the picking team, as well as the scissors and saws brought by the trimming team, are uniformly disinfected before use. Scissors and saws can be sterilized with medical alcohol, sodium hypochlorite, potassium permanganate, etc., and can also be boiled in boiling water. 【Disclaimer】The content of this article, personal views, for reference only!
