A Field experiment was performed using artificial infection with a highly pathogenic isolate of Fusarium subglutinans the causal agent of sugarcane pokkah boeng (PB) disease. The effects of foliar spray of plants by certain microelements on PB disease severity (DS), cane yield and juice quality of sugarcane at two consecutive seasons were studied. The foliar spray sugarcane variety G.T. 54-9 with each of zinc (Zn), manganese (Mn) and iron (Fe) individually or in mixture (Zn + Mn + Fe) significantly reduced the DS compared to the control plants. Applying each microelement individually was less effective in the reduction of the DS compared to microelements mixture application. The incidence of the disease decreased with increasing the spray frequency. Three foliar sprays gave the highest reduction of DS compared to one or two sprays. Spraying with the tested microelements either individually or in mixture significantly increased the net cane yield, the sugar yield and recovery percentage in sugarcane juice, as well as raised the values of reducing sugar percentage. The greatest increase of reducing sugar percentage was obtained by mixture applications followed by single application in both seasons. According to our results, microelements spray holds a great promise to enhance resistance in sugarcane plants against PB disease and to increase both cane yield and quality of sugarcane juice.

This study aimed to evaluate the bio-agent formulations of Trichoderma harzianum, Bacillus subtilis and Pseudomonas aeruginosa for the protection of lupine plants against wilt disease caused by Fusarium oxysporum f. sp. lupini . T. harzianum isolate (T1), P. aeruginosa isolate (P1) and B. subtilis isolate (B3) were the most effective ones in reducing the growth of F. oxysporum f. sp . lupini in vitro . Consequently, these isolates were used as bio-agent to control wilt on lupine plants in greenhouse experiments. The bio-agent isolates administered in the form of cells in broth media, powdered cells, and immobilized cells on sawdust as formulations were tested for their abilities to control lupine wilt in a greenhouse compared to Captan fungicide. Soil treatments with the three bio-agent formulations (broth medium or cells powder and sawdust) showed a markedly great reduction in wilt disease severity. Although all the formulations reduced the wilt disease severity compared to the water treatment, using the cells powder formulation of bio-agent reduced the wilt severity more than broth medium and sawdust formulations. In all formulations, T . harzianum (T1) exhibited the highest effect in the control of wilt compared with other bio-agent treatments. The sawdust and powder bio-agent formulations significantly reduced the disease severity of wilt on Lupine, as well as improved growth parameters (shoot, root, and plant length and seed yield/plant) of lupine plants compared with control treatment.
本研究旨在评估毛霉菌、枯草芽孢杆菌和铜绿假单胞菌的生物制剂在保护羽扇豆植物免受由Fusarium oxysporum f. sp. lupini引起的枯萎病方面的作用。T. harzianum 分离物（T1）、P. aeruginosa 分离物（P1）和 B. subtilis 分离物（B3）是体外减少羽扇豆镰刀菌生长最有效的分离物。因此，在温室实验中，这些分离物被用作控制羽扇豆植物枯萎病的生物制剂。以肉汤培养基中的细胞、粉末状细胞和锯屑上的固定细胞为制剂的生物制剂分离物在温室中控制羽扇豆枯萎病的能力与 Captan 杀菌剂相比进行了测试。使用三种生物制剂（肉汤培养基或细胞粉末和锯末）进行土壤处理后，枯萎病的严重程度明显降低。虽然与水处理相比，所有配方都能降低枯萎病的严重程度，但使用细胞粉生物制剂比肉汤培养基和锯末配方更能降低枯萎病的严重程度。在所有配方中，与其他生物制剂相比，T. harzianum（T1）对枯萎病的控制效果最好。与对照组相比，锯末和粉末生物制剂能明显减轻羽扇豆枯萎病的严重程度，并改善羽扇豆植株的生长参数（芽、根、植株长度和种子产量/株）。
