The mechanism of action of the herbicide
Primekstra TZ Gold 500 SC is a combined herbicide containing S-metolachlor and terbuthylazine. S-metolachlor is mainly absorbed by germinating weed shoots, and terbuthylazine by roots and partly by leaves. Thus, weeds die during the pre-emergence period, during and after the emergence of the culture.

Recommendations for the use of the drug Primekstra TZ Gold 500 SC
In order to improve the effect of the drug, it is recommended to apply under pre-sowing cultivation or under "Europak", but not deeper than 5 cm. When applying on weed ladders, prevent the growth of grass and dicotyledonous weeds to the phase of more than 2 leaves. When using the drug during adverse weather conditions such as frost, drought, etc., the effectiveness of the drug may decrease.

When applied in a row on corn and sorghum, the phase of weed development should not exceed 2 true leaves. It is not recommended to use if frostbite is expected within 2-3 days.

Can be mixed with other commonly used plant protection products on appropriate crops. However, in each specific case, the drugs should be checked for compatibility.
