１９９２～１９９３年在四川用一种土壤添加剂对烟草和番茄青枯病进行了小区防治试验，当剂量分别为７５克／株和１００克／株时，防治效果分别达５９．６％和７８．９％，显著优于同时参试的农药。盆栽试验结果显示，添加剂的防病机制主要是通过土壤中有益微生物群体而实现的，施用添加剂的土壤比对照土壤中的放线菌和芽孢杆菌的数量增加１０～１０３倍
From 1992 to 1993, a soil additive was used to control tobacco bacterial wilt and tomato bacterial wilt in Sichuan. When the dosage was 75 g / plant and 100 g / plant respectively, the control effects were 59.6% and 78% respectively. 9%, significantly better than the same time test pesticides. The results of pot experiment showed that the anti-pathogenic mechanism of additives was mainly achieved through the beneficial microorganism groups in the soil. The amount of actinomyces and bacillus in the soil with additives increased 10 ~ 103 times than the control soil
