番茄病毒病是番茄生产上的一种主要病害。在我市，无论是保护地还是露地都发生较重，常年造成损失１０ ％ —３０ ％ ，个别年份达５０ ％ 以上，严重影响番茄的产量和品质。笔者从１９９５ 年开始，依据植物营养学和植物病毒学原理，从改善营养生长出发，研制出高效、无毒、无残留病毒防治剂—“病毒除”，经小区试验和大田示范，防效均在８０ ％ 以上，且能有效提高番茄产量和品质。 Tomato virus disease is a major disease in tomato production. In our city, both the protected areas and open areas have occurred heavier, causing perennial losses of 10% -30%, more than 50% of individual years, seriously affecting the yield and quality of tomatoes. Starting from 1995, based on the principles of plant nutrition and plant virology, from the perspective of improving vegetative growth, the author developed an efficient, non-toxic and non-residual virus control agent - “virus addition”. After plot testing and field demonstration, More than 80%, and can effectively improve tomato yield and quality.
