Claim 1: use ingredients containing an effective amount of l-glufosinate and / or an acceptable salt herbicide in a glucose tolerant crop that contains less than 5 moles of d-glufosinate and / or an acceptable agricultural salt for that crop, According to the total amount of l-glufosinate and l-glufosinate salts, we can measure (I) strengthen the control of harmful plants, rather than double the amount of glufosinate race and / or acceptable salts used in agriculture； and (II) reduce the toxicity of plants, especially chloriside and / or reduce the growth,Encourage the use of organic additives at air temperatures of 18 ° C or higher, preferably 21 ° C or higher, compared to the same amount of glucose poisoning molecules and / or agricultural acceptable salts, in glucose tolerant fields, It is better to reach 24 ℃ or higher when measuring more than 2m above the ground. Claim 10: a method for controlling harmful plants in a glucose tolerant field, comprising the following steps: (a) providing a composition including L-glucose and / or its salts；The composition contains less than 5 mol% of d-glufosinate and / or agricultural acceptable salts, depending on the total amount of l-glufosinate and l-glufosinate salts, which can also be diluted with water optionally, (b) the organics are effectively used as herbicides and transferred from (a) to harmful plants； 1. Glucose resistant growth zone, its components are applied when the air temperature is 18 ℃ or higher, preferably 21 ℃ or higher, preferably 24 ℃ or higher when measuring 2 meters on the soil.Reivindicación 1: Uso de una composición que comprende una cantidad eficaz corno herbicida de L-glufosinato y/o sales aceptables para la agricultura de este en un cultivo en campo tolerante al glufosinato, donde la composición contiene menos de 5 mol.-% de D-glufosinato y/o sales aceptables para la agricultura de este, en función de la cantidad total de L-glufosinato y sales de este, para lograr (i) un aumento en el control de
