It is clearly seen from data that roots of Convolvulus arvensis L. have more and less intensive regenerative period during growing season. The more intensive period is in autumn, because in that time roots culminate nutrients, carbohydrate as starch and sugar. The less intensive regenerative or shoot-growing period is in spring, called "late spring bud dormancy". Experiments were conducted to get more information and further details about the regenerative capacity of roots close to and far from the collar of Convolvulus arvensis L. Root segments closer to collar have an intensive regenerative capacity than those ones further to collar. By data of Bakke et al. (1939) is well known, roots exhumed from deep soil layers are able to create shoots with low intensity. So finally we can exclaim that regenerative capacity is decreasing further to collar. Using mechanical weed control it is sufficient to till the upper layer of soil, but many times. Chemical treatments are most effective in the integrated weed control. It is clearly seen that auxin-type herbicide such as 2,4-D, fluroxipir, MCPA. dicamba give the best result. They gave 95% weed control effect used them separately or in combination with other herbicides. Combination of Banvel 480 S (dicamba) and Logran 75 WG (triasulfuron) introduced 95% weed control effect. Only one time got absolutely 100% weed control effect, in the case of Glyphosate active substance. Caused total plant destruction. Excellent result was given with the application of Pledge 50WP (flumioxazin). Herbicides mentioned above are absolutely allowed to take an important and significant part in chemical plant protection against Convolvulus arvensis L. Other herbicides like Granstar 75DF (tribenuron-methyl), Basis 75DF (rimsulfuron + tifensulfuron-methyl) and Huszár (jodosulfuron-methyl-sodium + mefenpir-diethyl) are not so effective against Convolvulus arvensis L., as compared to the previous ones.
从数据中可以清楚地看出，田旋花的根在生长季节有强度不同的再生期。再生强度较高的时期是在秋季，因为此时根中积累了养分，如作为淀粉和糖的碳水化合物。再生强度较低或枝条生长的时期是在春季，称为“晚春芽休眠”。进行了实验以获取更多关于田旋花靠近和远离根茎处根的再生能力的信息和进一步细节。靠近根茎的根段比远离根茎的根段具有更强的再生能力。根据Bakke等人（1939年）的数据可知，从深层土壤中挖出的根能够以较低强度长出枝条。所以最终我们可以说，再生能力越远离根茎越弱。使用机械除草时，只需多次翻耕上层土壤即可。化学处理在综合杂草控制中最为有效。可以清楚地看到，生长素类除草剂如2,4 - D、氟草烟、灭草灵、麦草畏效果最佳。单独使用或与其他除草剂组合使用时，它们能达到95%的杂草防除效果。480S型麦草畏（麦草畏）和75WG型乐田特（苯磺隆）组合能达到95%的杂草防除效果。只有在使用草甘膦活性物质的情况下，有一次绝对达到了100%的杂草防除效果，导致植株全部死亡。使用50WP型速收（氟嘧磺隆）取得了优异效果。上述除草剂在针对田旋花的化学植物保护中绝对可以发挥重要且显著的作用。与之前的除草剂相比，其他除草剂如75DF型巨星（苯磺隆）、75DF型阔世玛（烟嘧磺隆 + 甲基二磺隆）和胡萨尔（甲基碘磺隆钠盐 + 二乙基甲苯酰苯胺）对田旋花的效果没那么好。
