Optimal weed control under static and dynamic decision rules
从理论上推导并比较了动态和静态杂草控制决策规则，发现动态规则能提高农场利润并更有效控制杂草和草籽，而除草剂总用量不变。以玉米生产中阿特拉津控制狗尾草和苍耳为例，估计动态规则可使利润增加1.0%至1.4%。
Dynamic and static weed control decision rules are derived analytically and compared. The dynamic rule leads to increased farm profits and greater control of weeds and weed seeds than the static rule, while total herbicide use is unchanged. The magnitude of the differences is estimated for atrazine control of foxtail and cocklebur in corn production. Incorporating weed dynamics into weed control strategies increases farm profits between 1.0 and 1.4%.
