据报导世界某些花生产区由于叶斑病的危害,花生产量减少50%。在美国地区性的损失估计每年为5—10%,推荐的花生叶斑病防治策略,包括轮作、消毁花生残株和应用杀真菌剂。在美国最初的防治措施是用杀真菌剂,通常在播种后30—60天和收获前14—21天内进行为期10—14天叶面喷药。选择这样的防治方法,工作紧张且花钱多。本研究的目的是在应用各种杀真菌剂的基础上,对弗吉尼亚州叶斑病咨询方案和传统的14天防病计划进行年度纯利润比较。
It has been reported that peanut production has been reduced by 50% due to the threat of leaf spot in some flower-growing areas in the world. Regional losses in the United States are estimated at 5-10% per year, and recommended control strategies for peanut leaf spot include rotation, destruction of peanut stumps, and application of fungicides. The first control in the United States was to use a fungicide, usually for 10-14 days for foliar spray 30-60 days after sowing and 14-21 days before harvest. Choose such a prevention and treatment methods, work stress and spend more. The purpose of this study was to compare the annual net profit of the Virginia Leaf Spot Consultation Program with the traditional 14-day prevention plan, based on the use of various fungicides.
