- 农业科学 农业科学
背景情况:
- 这是一种细菌病,由Xanthomonas hortorum pv.v.引起. 胡卜 (Xhc),对全球胡卜产量产生重大影响,特别是由于其种子性质而导致的种子产量.
- 对细菌性植物疾病的有效治疗方法有限,目前的热水和二酸盐等方法对种子公司构成挑战.
研究的目的:
- 为了比较热水,低酸和化合物 (卡瓦克罗尔,蒂摩尔,尤根醇) 在消除感染胡卜种子的Xhc中的有效性.
- 确定一种有效和安全的种子治疗胡卜中的细菌病变,考虑病原体的消除,种子发芽和植物活力.
主要方法:
- 在体外和体内测试热水,二酸盐,卡瓦克罗尔,蒂摩尔和尤金醇对胡卜种子的治疗,其Xhc感染程度各不相同.
- 根据从发芽植物中消除Xhc,种子发芽百分比和植物活力来评估治疗的有效性.
主要成果:
- 在低感染率的种子中,使用1%的二和卡瓦克罗尔 (0.0196%-0.313%) 实现了完全消除Xhc.
- 在1%的甲和热水处理后,观察到中等感染种子中Xhc的显著降低.

Chemical Agents for Microbial Control
1.6K
Chemicals play important roles in controlling microbial growth by targeting microbial structures and functions as sanitizers, antiseptics, disinfectants, and sterilants.Alcohols are commonly used sanitizers, effectively disrupting lipid membranes, which compromises cell integrity. They are also used as antiseptics and disinfectants due to their rapid action and versatility.Phenols and their derivatives phenolics , known for denaturing proteins and disrupting cell membranes, are particularly...

Biological agents offer an effective means of controlling microbial growth by leveraging natural processes like predation, competition, and the secretion of antimicrobial substances.Predatory bacteria such as Bdellovibrio species target and kill pathogens like Salmonella and E. coli. They are widely used in poultry farms to control infections. Myxococcus species help combat plant-pathogenic fungi. These naturally occurring predators serve as eco-friendly alternatives to chemical pesticides and...

Biopesticides offer a sustainable alternative to chemical pesticides, utilizing microbial agents to control agricultural pests. Bacillus thuringiensis (Bt) is a widely employed bacterium known for its potent insecticidal activity. Bt biopesticides are favored for their specificity to insect pests, minimal environmental impact, and natural degradability.Mechanism of Bt Toxin Action Bt produces insecticidal crystal (Cry) proteins during its sporulation phase. These proteins form parasporal...
