目前,病害仍是花生产量能否持续上升的一个主要制约因素。通过美国十个花生生产州的花生病害损失估算可以看出,1984年新墨西哥州花生因病害造成的损失为5.25％,而1985年俄克拉荷马州的损失则为27.15％。由于病害的严重度是依赖于几种环境因素同其它因素的互作,如此同时也影响着病原菌和植株体,所以发病程度足以感病的种类、田间情况和各生产州的环境因素的不同而非一致。在经济上到底要化费几百万美元才能减轻病害,目前还不清楚。但通过制定布效的病害防治 At present, the disease is still a major constraint on the sustainable growth of peanut production. Estimates of the loss of peanut disease from ten peanut-producing states in the United States show that loss of peanuts in New Mexico in 1984 was 5.25% due to disease, compared with 27.15% in 1985 in Oklahoma. As disease severity is dependent on the interaction of several environmental factors with other factors, and thus affects both pathogens and plant body, the degree of disease is sufficient for the type of susceptible, field conditions and environmental factors in each producing state Not consistent. It is still not clear that the economy will have to spend millions of dollars in order to reduce the disease. But through the development of effective disease prevention and control
