Dermal in vitro penetration of methiocarb, paclobutrazol, and pirimicarb [PDF]

Occupational and Environmental Medicine, 2000
OBJECTIVESThe dominant route of occupational exposure to pesticides in horticulture is dermal. However, preventive measures are seldom used when handling plant cultures recently treated with pesticides, thus causing significant dermal exposure and potential absorption.

The optimization of crop response to climatic stress through modulation of plant stress response mechanisms. Opportunities for biostimulants and plant hormones to meet climate challenges.

New Phytologist, Volume 249, Issue 1, Page 130-151, January 2026.
Summary This review discusses the use of agronomic management practices to enhance crop stress resilience to climate stress through the modulation of natural plant growth regulatory pathways. The use of biostimulants or plant hormones to improve crop resilience is subject to strict regulatory oversight if changes in the regulation of plant growth are ...

Transporte do paclobutrazol em colunas de solos Paclobutrazol transport in soil columns

Revista Brasileira de Ciência do Solo, 2008
O paclobutrazol (PBZ) é um regulador de crescimento utilizado em sistemas agrícolas com o propósito de controlar o crescimento vegetativo, estimulando a capacidade reprodutiva das plantas. Esse regulador de crescimento permanece ativo no solo por muito tempo, e sua meia-vida varia com o tipo de solo e as condições climáticas, podendo afetar severamente

MicroRNA156 and its targeted SPL genes interact with the photoperiod, vernalization, and gibberellin pathways to regulate wheat heading time

The Plant Journal, Volume 125, Issue 1, January 2026.
SUMMARY Heading time has a large impact on adaptation to different environments and crop productivity. In this study, we characterized the effect of the endogenous age pathway on heading time and its interactions with the photoperiod and vernalization pathways in the leaves of tetraploid wheat (Triticum turgidum ssp. durum).

Response of paclobutrazol treatment on flowering, fruit maturity, yield and quality of mango (Mangifera indica) cv Totapuri

The Indian Journal of Agricultural Sciences, 2014
A field trial was conducted at Indian Institute of Horticultural Research Bangalore during 2007-2011 to study the effect of different doses and time of application of paclobutrazol on flowering, fruiting behavior and quality of 22 years old mango ...

The LARGE1 controls grain size by repressing the interaction between PGL2 and APG in rice

The Plant Journal, Volume 125, Issue 2, January 2026.
SUMMARY Grain size has long been recognized as a key determinant of yield potential in crops. Understanding the mechanisms governing grain size is critical for breeding high‐yielding varieties. In a previous work, we revealed that the RNA‐binding protein LARGE1 acts as a negative regulator of grain size and weight in rice.

Increase in biodegradation of paclobutrazol in soils [PDF]

BMC Proceedings, 2014
Background Paclobutrazol is a regulator of vegetal growth that remains active in the soil and can affect the growth and the development of subsequent cultures. Experiments in two soils (A and B) with and without addition of inoculum or mineral medium were performed to investigate the biodegradation of paclobutrazol.

Shoulder season plant growth regulator programs for Poa annua control in creeping bentgrass putting greens in Tennessee

Crop, Forage &Turfgrass Management, Volume 11, Issue 2, December 2025.
Abstract Many golf course superintendents rely on plant growth regulators (PGRs) as a primary means of managing Poa annua L. in creeping bentgrass (Agrostis stolonifera L.), particularly the early‐stage gibberellic acid inhibitor paclobutrazol (Trimmit 2SC; Syngenta Professional Products). While herbicides for Poa annua control are often applied during

Residue of Paclobutrazol and Its Regulatory Effects on the Secondary Metabolites of Ophiopogon japonicas

Molecules, 2019
Currently, paclobutrazol is excessively used in the planting process of Ophiopogon japonicus (O. japonicus) due to its important role in regulating the growth of tuber roots, ultimately increasing the yield and shortening the growth cycle of Ophiopogonis

Fertiliser supplementation with a PGR complex of chlormequat chloride (CCC) and paclobutrazol (PBZ) alters Cannabis sativa growth

New Zealand Journal of Crop and Horticultural Science, Volume 53, Issue 5, Page 3113-3123, December 2025.
ABSTRACT Cannabis (Cannabis sativa) is a high‐value crop, wherein growth within controlled environments is common for the purposes of maximising yield, quality, and uniformity, however, uncontrolled‐growth in proximity to artificial lighting can compromise yields. Within the floricultural industry it is common practice to apply plant growth regulators (
