Plant Infection

Plant infection occurs when environmental factors compromise a plant's physiological processes, leading to structural, growth, or functional disruptions. In recent years, bacterial, fungal, and viral infections have increasingly contributed to plant diseases, affecting crops at various stages of agricultural production. Under favorable conditions, disease prevalence can reach 70–80% of the plant population, resulting in yield losses of up to 80–98%. Although plants possess innate cellular immunity, certain phytopathogens can evade this defense mechanism, enabling successful infection and disease progression.

    Wheat Germ Agglutinin (Fluorescein)
    Wheat Germ Agglutinin (WGA) Fluorescein is a classic fluorescent label that specifically binds to sugar residues such as N-acetylglucosamine, N-acetylneuraminic acid and sialic acid. Wheat Germ Agglutinin Fluorescein performs regionally differential fluorescent staining of the ocular surface epithelial glycocalyx to assess its integrity, and causes no damage to the eye at safe concentrations. Wheat Germ Agglutinin Fluorescein is also used for staining structures including red blood cells, cultured cells, bacteria and pine wood nematodes, and facilitates the isolation of wheat-associated plant-growth-promoting rhizobacterial strains. Wheat Germ Agglutinin Fluorescein can be applied to the detection of ocular glycocalyx integrity and the research of related diseases such as pine wilt disease.

    Tembotrione 335104-84-2 99.41%
    Tembotrione is a herbicide belonging to the HPPD (dioxygenase) inhibitor class with crop selectivity. Tembotrione effectively controls a variety of weeds including broadleaf and gramineous species by disrupting carotenoid synthesis, which leads to chlorophyll degradation and leaf whitening. Mixing Tembotrione with isoxaflutole or adding surfactants optimizes its efficacy and reduces phytotoxicity, with no residual impact on subsequent cruciferous crops, thus helping to increase maize grain yield. The activity of Tembotrione decreases under drought conditions, and under specific conditions (such as double-dose treatment), it may cause reversible yellowing and even yield reduction in crops such as poppy.
