With the modernization of agriculture, herbicides have played a vital and irreplaceable role in controlling farmland weeds and protecting agricultural production.

Mepiquat chloride is used on a wide range of crops, including cotton, wheat, rice, peanuts, corn, potatoes, grapes, vegetables, legumes, and flowers.

When formulating products, customers typically consider the pH levels of fertilizers, which can limit their choice of plant growth regulators. Brassinolide is a novel regulator with a neutral pH, allowing it to be combined with fertilizers and pesticides across the entire pH spectrum—whether acidic or alkaline.

During the process of fruit color change, chlorophyll gradually breaks down and disappears under the action of hydrolases; carotenoid levels increase slightly, while anthocyanins are produced in large quantities and accumulate continuously.

Regarding peach blossom and fruit thinning, spraying Ethephon at a concentration of 200 mg/kg eight days after flowering, or a Naphthylacetic Acid (NAA) solution at 40–60 mg/kg between 20 and 45 days after flowering, has proven effective. Trials on yellow peaches showed that spraying Ethephon at 300 mg/kg during full bloom yielded excellent thinning results.

Key Agricultural Uses of Ethephon
Promotes fruit ripening:It is the most widely used fruit-ripening agent. Applied to crops such as tomatoes, apples, mangoes, and bananas, it accelerates color change and ripening by 1–2 days, facilitating centralized harvesting and long-distance transport.

Both Indole Butyric Acid and Sodium 1-Naphthyl Acetic Acid promote rooting of cuttings. However, for some plants that are difficult to root, their effects are poor when used alone. Mixing Indole Butyric Acid and Sodium 1-Naphthyl Acetic Acid in a specific ratio can achieve satisfactory results.

DA-6 can increase the content of chlorophyll, protein, and nucleic acid in plants, as well as the photosynthetic rate. It also increases the activity of peroxidase and nitrate reductase, accelerates carbon and nitrogen metabolism, enhances the absorption of water and fertilizer and the accumulation of dry matter

Sodium 1-Naphthyl Acetic Acid(Na-Naa) is a broad-spectrum plant growth regulator that rapidly promotes cell division and expansion (fruit-enlarging agent, fruit-swelling agent), induces adventitious root formation (rooting agent), and regulates growth, promotes rooting, budding, flowering, prevents flower and fruit drop, forms seedless fruits, promotes early maturity, and increases yield.
