As July begins, temperatures rise and rainfall becomes abundant across the country, marking a period of rapid crop growth. July is a critical month for rice; achieving high yields requires scientific field management. Here are five key points for managing rice fields during this time:

In test plots treated with Pinsoa Root King, *Rehmannia* plants exhibited exceptional root growth; the root systems were well-developed with a prolific proliferation of fibrous roots, and the main roots were thick and uniform.

Ethephon is a synthetic, low-toxicity plant growth regulator. Its primary function involves releasing ethylene upon entering the plant to modulate physiological processes; its key effects are as follows:

External color is a crucial indicator of fruit quality and a primary selling point for commercial fruit; consequently, it is highly valued by growers, traders, and consumers alike.
The type, content, and distribution of anthocyanins determine fruit color. Anthocyanin synthesis in the fruit skin increases as chlorophyll degrades, and varieties with deeper red coloration typically possess higher anthocyanin levels.

Treating kiwifruit cuttings with IBA-K yields superior rooting results. Trials using a rapid dip method—immersing *Actinidia chinensis* hardwood cuttings in a 5,000 mg/L IBA-K solution for 3 seconds—achieved survival rates of 81.9%–91.9%, with an average of more than 10 roots per cutting. For softwood cuttings, a rapid dip in 500–1,000 mg/L IBA-K resulted in rooting rates of 95%–100%.

Brassinolide has been in use for a long time, available in a wide range of types, grades, and price points. However, some users wonder why the results aren't as miraculous as rumored. Did they buy a counterfeit product, or are they using it incorrectly?

Flower and fruit thinning agents are plant growth regulators that induce the abscission of a portion of flower buds or young fruit. Commonly used agents include dinitro-o-cresol (DNOC), 1-Naphthylacetic acid (NAA), phenylacetamide, and ethephon.

Brassinosteroids respond to high-temperature stress by activating protective enzyme systems to maintain cell membrane stability, regulating stomatal opening and closing to reduce water loss, and promoting cell division to accelerate the repair of damaged tissues.

For summer crop drought resistance, the preferred choices are Brassinolide, DA-6, Sodium Nitrophenolates (Atonik), and Fulvic Acid-based regulators; combining these with foliar sprays of potassium dihydrogen phosphate yields the best results.
