El crecimiento y metabolismo de Bacillus amyloliquefaciens produce antibióticos de bajo peso molecular y péptidos proteicos antibacterianos y otras sustancias activas, que pueden inhibir bacterias y nematodos patógenos. La mayoría de las sustancias activas de los metabolitos son térmicamente estables, insensibles a la radiación ultravioleta y al tratamiento con proteasas. Resistente a ácidos y álcalis y otras características.

Las enzimas extracelulares producidas por Bacillus amyloliquefacienss incluyen principalmente fitasa, quitinasa, glucanasa, proteasa, amilasa, quimosina, etc. Los principales metabolitos de lipopéptidos incluyen surfactina (surfcatian). También se producen sustancias activas antagonistas como fengicina, litarina y Bacillo-my-cinD. Además, también se produce la hormona del crecimiento vegetal ácido indol-3-acético (IAA).

El caldo de fermentación de Bacillus amyloliquefaciens se puede convertir en preparaciones biológicas y aplicarse a raíces, ramas, hojas, flores, frutas y verduras de plantas para la prevención y el tratamiento de enfermedades. Las preparaciones de Bacillus amyloliquefaciens también promueven el crecimiento de las plantas, inhiben los nematodos y controlan la contaminación del agua.

LIN-AM tiene tanto las características de las raíces de las plantas en general como las características de los hongos obligados. Tiene una amplia gama de aplicaciones y puede formar una relación simbiótica con la mayoría de las plantas.

LIN-AM puede promover la absorción de nutrientes del suelo por los cultivos, promoviendo así el crecimiento de los cultivos, aumentando el rendimiento y mejorando la calidad. También puede mejorar la resistencia de los cultivos a las enfermedades e inhibir la aparición de enfermedades transmitidas por el suelo alrededor de las raíces.

Effects and characteristics:
Inhibit plant growth, make plants dwarfed and compact, and are used for ornamental plant shaping. Increase plant resistance, including resistance to pests and diseases, lodging, and drought. Promote plant flower bud differentiation, improve fruit setting rate and fruit quality.

Precautions:
The concentration and method of using uniconazole should be adjusted according to plant varieties and growth goals (such as dwarfing, flower promotion, etc.). It has a certain residue in the soil, which may affect sensitive crops in the following crops, and reasonable crop rotation is required. Uniconazole cannot be mixed with strong alkaline substances to avoid loss.

Efficacy and characteristics:

It promotes plant cell elongation and division and is an auxin necessary for plant growth. It promotes rooting and plays a key role in cutting propagation and plant root development. It regulates the growth direction of plants, such as phototropism and geotropism.

Precautions:

Indoleacetic acid is easily decomposed under light, so after use, try to avoid strong light exposure to plants, or choose to use it in the evening when the light is weak. Different plants react differently to indoleacetic acid, and the concentration needs to be adjusted according to the plant species and growth stage. Indoleacetic acid should be stored away from light and at low temperatures to prevent its decomposition and ineffectiveness.

Efficacy and characteristics:

Promotes plant leaf shedding, used before cotton and other crops are harvested, and is convenient for mechanical harvesting. It promotes plant cell division and elongation, and also has a certain effect on fruit enlargement. Enhances plant resistance and reduces environmental stress damage to plants.

Precautions:

When thiazuron is used to defoliate crops such as cotton, pay attention to the time of use. It should not be used too early or too late, otherwise it will affect the yield or defoliation effect. It is irritating to the human body, so take good protection during use.
When thiazuron is mixed with other pesticides or fertilizers, precipitation, discoloration and other phenomena may occur, and compatibility needs to be paid attention to.

Efficacy and characteristics:

Promotes plant seed germination and rooting, and improves seed germination rate. Enhances plant photosynthesis, makes plants grow strong, and increases crop yields. Improves plant resistance and maintains plant growth in adverse environments.

Precautions:

Triacontanol may be effective with a small amount, so the dosage must be accurately controlled to avoid waste and pesticide damage. It should be used in sunny weather, which is conducive to plant absorption. Rainy days may affect the effect.
When it is mixed with other regulators or fertilizers, synergistic effects may occur, which requires advance testing.

Efficacy and characteristics:

Induce plant disease resistance, activate the plant’s own defense system, and resist fungal, bacterial and other diseases. Promote plant growth, increase plant chlorophyll content, and improve photosynthesis efficiency. Improve soil environment and promote the growth and reproduction of beneficial microorganisms in the soil.

Precautions:

The quality of chitosan oligosaccharide varies greatly. When using it, pay attention to the pH value of the solution. It can work better within the appropriate pH range.
Chitosan oligosaccharide is best used during the critical period of plant growth (such as transplanting period and early stage of disease) to enhance plant resistance.

Efficacy and characteristics:

Used to promote plant rooting, and has better effects on some plant varieties that are difficult to root. When used as a herbicide, it can kill dicotyledonous weeds at high concentrations and is used for weeding in the fields of gramineous crops.
Preventing flowers and fruits from falling, it has a certain fruit-preserving effect in the cultivation of fruit trees such as citrus.

Precautions:

When 24-D is used as a herbicide, it is necessary to strictly distinguish between dicotyledonous and monocotyledonous plants to prevent pesticide damage to crops. When used to prevent flowers and fruits from falling, too high a concentration may cause fruit deformity, and the concentration must be accurately controlled.
During the operation, pay attention to prevent the agent from drifting and causing damage to surrounding non-target plants.

Effects and characteristics:
Induce plants to produce systemic acquired resistance to pathogen invasion, such as tobacco’s resistance to tobacco mosaic virus. Regulate the opening and closing of plant stomata to help plants reduce water loss during drought. Participate in the growth and development of plants, such as seed germination and root growth.

Precautions:
Salicylic acid may be toxic to plants at high concentrations, so it should be used strictly according to the recommended concentration. The effects of salicylic acid may be affected by environmental factors (such as temperature and humidity), so these factors should be considered when using it. Its metabolic process in plants is relatively complex, and excessive use may interfere with the normal physiological metabolism of plants.

Effective features:
Shorten internodes, short and strong plants, prevent leggy growth in corn planting. Increase lodging resistance and drought resistance of plants, improve crop survival ability. Promote reproductive growth, conducive to flower bud differentiation and fruit development.

Precautions:
The concentration of chlormequat should be accurate. Different plant varieties have different sensitivities to it. Too high a concentration will stagnate plant growth. Pay attention to the use period. It is generally used in the early stage of plant growth to inhibit vegetative growth and promote reproductive growth. It cannot be mixed with alkaline pesticides, otherwise the efficacy will be reduced.
