RATNA-TEMBO
Tembotrione 34.4% SC
RATNA-TEMBO (Tembotrione 34.4% SC) is a selective post-emergence HPPD-inhibitor herbicide from Ratnakar India Ltd, Ahmedabad — India's trusted agrochemical manufacturer, supplier, and exporter. Tembotrione inhibits 4-hydroxyphenylpyruvate dioxygenase (HPPD) enzyme, disrupting carotenoid biosynthesis causing bleaching and death of target weeds in maize. RATNA-TEMBO controls Echinochloa sp., Trianthema portulacastrum, and Brachiaria sp. Manufactured and exported by Ratnakar India from Gujarat, RATNA-TEMBO is a precision post-emergence herbicide for progressive maize farmers seeking effective weed control with high maize crop selectivity and convenient low-volume application.

FAQ for RATNA-TEMBO
What weeds does RATNA-TEMBO control in maize?
RATNA-TEMBO controls Echinochloa sp., Trianthema portulacastrum (horse purslane), and Brachiaria sp. — important grassy and broad-leaf weeds causing yield losses in maize crops.
How does Tembotrione work?
Tembotrione inhibits HPPD enzyme binding, disrupting carotenoid pigment synthesis in weeds. Without carotenoid protection, chlorophyll is destroyed by light causing rapid bleaching and weed death.
Is RATNA-TEMBO selective for maize?
Yes, RATNA-TEMBO is highly selective for maize due to rapid metabolic detoxification of Tembotrione in maize plants through glucosylation, making it safe when applied at recommended rates.
When should RATNA-TEMBO be applied in maize?
Apply RATNA-TEMBO post-emergence when maize is at 3–5 leaf stage and weeds are small and actively growing. Add a sticker for better coverage and use 57.5–230ml per acre as directed.
Does RATNA-TEMBO control Trianthema weed in maize?
Yes, RATNA-TEMBO is specifically effective against Trianthema portulacastrum (horse purslane) — an important broad-leaf weed in maize that is often difficult to control with standard maize herbicides.
