植物的病毒病不论过去还是现在,都是属于一种难治的病害。以往通常采用切断传染联来行进防治,不仅方法繁琐,而且效果甚少。至今较能奏效的防治措施还是采用抗病品种,但是,目前能在生产上应用的品种却很少。为此,利用弱病毒防治作物病毒病的研究日益发展,其中,尤其是利用弱病毒来防治番茄的病毒病已经在生产中取得了实效。 Plant virus disease, whether past or present, is a refractory disease. In the past usually cut off the contagion to travel prevention and control, not only tedious method, but little effect. So far more effective control measures or the use of disease-resistant varieties, however, the current varieties can be applied in the production is very small. To this end, the use of weak viruses to combat crop disease is increasingly developed, of which, especially the use of weak viruses to control tomato virus disease has been made in the production of effective.
