杀菌剂方面知道

Mode of action and target site or mechanism of action:

动作的模式(MOA) describes the biochemical processes by which the fungicide poisons the fungus (for example, disrupting cell wall synthesis)。 Target site of action or mechanism of action is the exact location of inhibition, such as interfering with the activity of a specific enzyme within a metabolic pathway.

选择 and selection pressure:

选择 is the process by which control measures favor resistant individuals over susceptible ones (see 理解性)。 选择压力 refers to the intensity of the selection.

Protectant or 渗透剂 Fungicide:

Internal Server Error

渗透剂 (也称为“特定地点”)杀菌剂 are absorbed into plants following application and also function as a protectant fungicide at the site of contact. They are generally considered systemic fungicides, but they have different degrees of systemic movement:

本地系统 fungicides move only a short distance such as within the leaf to which it is applied.

椎板的杀菌剂

椎板的杀菌剂 (疾病管理 Strategies – Purdue Extension)

椎板的杀菌剂 move through the leaf from one side to the other.

Xylem Mobile Fungicides

木质部移动杀菌剂

木质部移动杀菌剂 move upward in plants and outward to the periphery of leaves with water through the xylem, the water conducting tissue of the plant. This is known as acropetal movement

Amphimobile Fungicides

amphimobile /真正的全身 fungicides

amphimobile /真正的全身 fungicides move both upward through the xylem, and downward through the phloem, the food conducting tissue of the plant. These fungicides are described as amphimobile. Few fungicides are fully systemic.
