Description
Action Mechanism and Selectivity
"Vayap Extra SC" by Basf S.A. is a systemic selective herbicide that functions primarily as a soil barrier. The active ingredient, Pendimethalin, belongs to the dinitroaniline class and works by inhibiting mitosis in the meristematic tissues of emerging weeds. This action effectively halts the development of both annual broadleaf and grass weeds before they break through the soil surface.
Technical Specifications and Application
The suspension concentrate formulation ensures high stability of the working solution and uniform distribution across the soil profile. As a pre-emergence herbicide, it establishes a "protective shield" in the topsoil layer, which remains active provided there is sufficient soil moisture. To achieve maximum efficiency, the product is applied once per season, with a dosage rate ranging from 2.0 to 3.0 L/ha, depending on soil type and weed pressure.
Benefits for Vegetable Crops
The selectivity of the composition allows for safe application on various vegetable crops, including onions, garlic, tomatoes, carrots, cabbage, cucumbers, potatoes, and strawberries. Manufactured by Basf S.A. (Brazil), the product falls under toxicity class 3, ensuring a predictable agronomic cycle when handling instructions are followed. By preventing weed germination early on, the herbicide reduces competition for light and nutrients, allowing the crops to maximize their growth potential from the very beginning.

By type of action
By type of action
Depending on their ability to move through living tissues, herbicides are divided into contact and systemic. Contact herbicides cause local damage to plant tissue upon contact, which dies or gradually degrades. This action does not always completely destroy the plant; often, its... |

By application method
Based on the method of application, herbicides are divided into foliar, soil, and root herbicides. Foliar herbicides are applied to vegetative plants and act through their above-ground organs. The main method of application for such preparations is spraying using sprayers or airp... |

By Application Timing
By Application Timing
Herbicides are classified according to application timing into pre-emergent and post-emergent herbicides. Pre-emergent herbicides are mostly soil-applied or granular formulations applied before the emergence of crop plants. They are applied either pre-sowing (during pre-sowing cu... |
