Recent fertilizer price increases have caused commercial farmers to consider alternative input sources for select nutrients. The blending of potassium chloride with potassium sulfate or sulfate of potash magnesia is a scenario that is commonly...

Cigar wrapper tobacco is a new crop to North Carolina, and research-based fertilizer recommendations are needed to assist farmers with commercial production. Nitrogen (N) and potassium (K) rate trials were conducted in four locations across North...

Maleic hydrazide (MH) remains a critical component of sucker control programs in US tobacco production systems. However, MH residues remain a strong critique of tobacco sourced from the region. The purpose of our research was to evaluate high-output...

Recent investigations of Cyantraniliprole, Flutriafol, and S-metolachlor applications have been conducted in flue-cured tobacco on behalf of the Pesticide Committee of the Tobacco Workers Conference. Field trials were conducted in five North Carolina...

Maleic hydrazide (MH) is a systemic plant growth regulator used to control “sucker” growth in flue-cured tobacco. Conventional application methods involve applying MH over the top of the plant to ensure proper coverage and effectiveness. But this...

The propensity for flue-cured tobacco leaves to retain or improve their visual quality and economic value over an extended period of time is referred to as “holding-ability”. General holding-ability models that are specific to popular varieties are...

An increasing number of flue-cured tobacco farmers are including water soluble fertilizer products in transplant water applications. The goal of these starter fertilizer programs is to supply a small quantity of phosphorus, which may stimulate...

Proposed standards from the US-FDA suggest that nicotine should be lowered to non-addictive concentrations in cigarettes (0.3 to 0.5 mg g-1). One such method for lowering nicotine in finished products is to source leaf material with low...

An increasing number of flue-cured tobacco farmers are including water soluble fertilizer products in transplant water applications. The goal of these starter fertilizer programs is to supply a small quantity of phosphorus, which may stimulate...

Connecticut broadleaf cigar wrapper tobacco is a new crop to North Carolina. As such research-based fertilizer recommendations are needed to assist farmers with commercial production. Nitrogen (N) and potassium (K) rate trials were conducted in four...
