沙棘干缩病是危害沙棘的主要病害.病原菌有性阶段为座囊菌目、座囊菌科、沙棘双丛孢座属、沙棘双丛孢座菌;无性阶段为胡颓子小色二孢属.干缩病菌在沙棘生长前期侵染,生长后期发病.杀抑菌试验表明,抑菌效果以56%靠山水分散粒剂、复配制剂KB最佳;抑菌圈直径结果表明以复配制剂KB、50%农利灵抑菌效果最好.田间小区试验结果表明复配剂KB防治效果较高,但几种药剂防效达不到要求,因此,选择特性农药及提高药剂渗透性是防治沙棘干缩病的主要方面.
Seabuckthorn dry shrinkage disease is the main damage to seabuckthorn.The pathogenic stages of the genus Vesicular, Vesicular Division, Seabuckthorn bicarpus, seabuckthorn Chlamydomonas reinhardtii; asexual stage of Elaeagnus small color spores Bacillus subtilis in the early growth of seabuckthorn infection, the incidence of late growth.Antimicrobial inhibition test showed that the antibacterial effect of 56% rely on water dispersible granules, compound preparation KB best; inhibition zone diameter results show that the compound Formulation KB, 50% naringale the best antibacterial effect.Field plot test results show that the compound KB to control the effect of higher, but several agents failed to meet the requirements, therefore, choose the characteristics of pesticides and enhance the permeability of the drug is Prevention and treatment of seabuckthorn dry shrinkage of the main aspects.
