1985年在乔治亚州出现了因西红柿斑萎症tospovirus病毒引起的烟草斑萎症。自1995年以来,因斑萎症造成的损失已超过了所有其他病害损失的总和。单株烟草的损失预计在25%到30%,更大的损失亦属常见。标准的化学防治(acibenzolar-S-methyl和im- idacloprid)可减少40-50%的损失。虽然该控制水平效果显著,但经常仍显不足。进一步减少斑萎症的方法正在不断的探索之中。本文是对众多此类探索之一所作的总结。
In 1985, spot blight caused by tospovirus in tomato spotted blight occurred in Georgia. Since 1995, the damage caused by the blight has exceeded the sum of all other disease losses. Loss per plant is estimated at 25% to 30%, and greater losses are also common. Standard chemical control (acibenzolar-S-methyl and im-idacloprid) can reduce the loss of 40-50%. Although this level of control is significant, it is often not sufficient. Methods to further reduce blooms are constantly being explored. This article is a summary of one of many such explorations.
