PERSEI 480 EC

Selective systemic herbicide for control of annual broadleaf and grass weeds

Category: Herbicides

Active ingredient:

clomazon, 480 g/L

Formulation:

emulsion concentrate

Packing:

1 L,5 L,10 L

Mode of action:

The product inhibits protein synthesis in plant cells, leading to disruption in chlorophyll production and causing plant death. Thanks to advanced surfactants, the herbicide quickly penetrates through the leaves and other green parts, effectively spreading throughout all plant organs, reaching the root system.

Field of usage

Crop	Dose rate, l/ha	Weed	Terms of application
Rape	0,15–0,2	Annual broadleaf weeds and some grass weeds.	Soil spraying before sowing, during or after sowing, but before crop emergence.
Soybean	0,2		Soil spraying before sowing, during sowing, or after sowing but before crop emergence.
Soybean	0,25-0,5		Spraying of crops at the 1-3 true (trifoliate) leaf stage

Compatibility

Compatible with most herbicides, insecticides, and fungicides when the application timing aligns. However, it is necessary to check the compatibility of the products in each specific case. It is used in tank mixtures with products based on propyzamide and metazachlor.

Application features

The optimal time for application is immediately after sowing, before crop emergence. The soil should be well-prepared with a fine structure: the presence of large clods or significant amounts of plant residue reduces effectiveness due to increased adsorption surface. During application, it is essential to ensure even and complete coverage of the entire area.

After application, the product forms a protective layer in the upper soil horizon, providing control of germinating weeds for 6-8 weeks. In rapeseed crops, under conditions of increased humidity or lower temperatures, temporary whitening of the first pair of leaves may occur, which does not affect the further development of the crop — the coloration quickly recovers.

The recommended application rate for the working solution is:

for soil application — 200–300 l/ha;
for post-emergence application — 150–250 l/ha

For soil application, inter-row cultivation is not recommended within 2–3 weeks after treatment, as it may damage the formed protective layer. The duration of protective action exceeds 30 days.

Product’s advantages

High effectiveness against annual grasses and a number of key broadleaf weeds.
Has a pronounced and long-lasting soil action, effectively controlling subsequent weed waves.
Guarantees stable protective effect for 6–8 weeks, depending on weather conditions.
Ideally suited for use in tank mixtures with soil herbicides to expand the spectrum of action.
Minimal dependence on soil moisture.
