1、Effects of Paclobutrazol on Reproductive and Vegetative Traits of

For producing single-flower phalaenopsis, a foliar spray of 750 mg·L−1 PP333 is recommended approximately a month before moving the plants to cooler conditions, followed by truncation, retaining only the first flower.

Effects of foliar application of paclobutrazol and seaweed fertilizer

For high yield and quality of peanut, field experiments were conducted in 2012 and 2013 to study the effects of paclobutrazol (PBZ) and seaweed fertilizer (SM6) on peanut. 3 cultivars KB008 (high protein), Hua 17 (high oil), and Nongda 818 (high O/L) were used as materials. Results showed that PBZ treatment significantly increased pod yield by ...

Paclobutrazol as a plant growth regulator

In this review, the current knowledge and possible applications of PBZ, which can be used to improve the growth, yield and quality of crops, have been reviewed and discussed. The role of PBZ to mitigate the harmful effects of environmental stresses in crops is also examined.

Advances in Crop Science and Technology

Paclobutrazol (PBZ) is a plant growth retardant and triazole fungicide. It is a known antagonist of the plant hormone gibberellin. The largest group of plant growth retardants consists of chemicals antagonistic to gibberellins (GA), the hormone that is responsible for plant growth.

(PDF) Effect of Spraying Paclobutrazol (PP333) on Yield and Fruit

ABSTRACT Six concentrations of Paclobutrazol (PP333) were experimented (0, 10, 30, 60, 90, 120 ppm) as foliar spray on three years old Crimson seedless grape vines grown in private orchard at...

EFFECTS OF PACLOBUTRAZOL (PP333) ON VEGETATIVE AND FLORAL DEVELOPMENT

Foliar applications of PP333 at low concentrations were highly effective in suppressing vegetative growth in low chill nectarines during the DWIII phase of fruit development.

Combined Effects of Fertilizer, Irrigation, and Paclobutrazol on

Combinations of fertilizer rates, foliar N sprays, irrigation practices, and paclobutrazol were studied to determine how much they could alter and/or improve mango (Mangifera indica L.) growth, flowering, and yield.

Paclobutrazol (PBZ) and its Metabolic Function in

Our results suggested that paclobutrazol could efficiently be used to enhance root-physiological and morphological characteristics, resulting in higher grain yield.

Foliar fertilizer and paclobutrazol (also known as PP333) are two distinct plant growth regulators with different mechanisms of action and application conditions. In agricultural production, these substances are sometimes used together, but their compatibility depends on multiple factors, including crop type, growth stage, environmental conditions, and more. Below is a detailed discussion of their combined use.

Function and Application of Foliar Fertilizer

Foliar fertilizer is a nutrient solution applied directly to plant leaves. It is absorbed through the leaves into the plant, rapidly elevating internal nutrient levels, enhancing photosynthesis, and boosting yield. Foliar fertilizers typically contain macronutrients like nitrogen (N), phosphorus (P), and potassium (K), as well as microelements such as iron (Fe), zinc (Zn), and copper (Cu). Their use accelerates crop growth, improves fruit quality, and strengthens disease resistance.

Function and Application of Paclobutrazol

Paclobutrazol is a plant growth inhibitor that suppresses cell division, slowing plant growth. It is commonly used to prevent excessive stretching (spindling) in fruit trees, vegetables, and ornamental plants, particularly during vigorous spring shoot growth. Paclobutrazol reduces leaf quantity, increases fruit size, and enhances fruit quality.

Feasibility of Combining Foliar Fertilizer and Paclobutrazol

1. Complementarity: In certain scenarios, foliar fertilizer and paclobutrazol can complement each other. For example, after pruning fruit trees, foliar fertilizer quickly replenishes nutrients, while paclobutrazol controls new shoot growth, promoting compact branches and improved fruit quality.

2. Avoiding Side Effects: Sole use of foliar fertilizer may lead to nutrient excess and disrupt soil balance, while excessive paclobutrazol could overly stunt growth. Combined use mitigates these risks by balancing nutrient supply and growth regulation.

3. Crop-Specific Needs: The combination can address crop-specific issues. For instance, during spring shoot growth in crops prone to spindling, both substances can be applied together. Similarly, during fruit enlargement, their joint use may enhance quality.

4. Environmental Adaptation: Effectiveness varies with climate. Local weather, temperature, and humidity must be considered to adjust dosage and timing for optimal results.

5. Economic Considerations: While combined use may be more effective in some cases, cost-efficiency depends on price differences between the two agents. If costs are similar, simultaneous application may not be necessary.

The combined use of foliar fertilizer and paclobutrazol is feasible but should be tailored to specific crops, growth stages, and environmental conditions. Dosage and application methods must align with crop requirements and local context to maximize benefits. Care should be taken to avoid overuse, side effects, and ensure adaptability to varying environments.
