In recent years, farmers have been facing a growing problem: strange weeds are appearing in greenhouses and are hard to remove once they take hold. These weeds are commonly referred to as "grass." The reason for this name comes from the small yellow flowers that appear on them. After flowering, the plant develops five pods, each containing tiny, flat, oval seeds with a red-brown color. When the fruit matures, it splits open along its back, and the seed is forcefully ejected, much like a jumping bean. This spreading mechanism allows the seeds to travel far and wide, making the weed difficult to control and leading to its nickname—“grass.â€
Scientifically, this weed is known as *Oxycaryum* and is commonly called shamrock. It belongs to the Oxymoraceae family, a group of dicotyledonous plants. Shamrock is a perennial herb that typically blooms between May and August, and its fruits develop from June to September. Due to its ability to reproduce both through roots and seeds, it spreads rapidly. Its small, numerous seeds make manual removal ineffective. Chemical control is often necessary, but it must be done carefully, especially when growing tomatoes.
When using herbicides, safety for the tomato plants must come first. After extensive research and testing, DuPont Baocheng has proven effective in controlling shamrock in tomato fields, with similar results seen in eggplants and peppers. DuPont Baocheng is a post-emergence herbicide used on crops such as corn, tobacco, potatoes, and tomatoes. It effectively targets annual grasses, sedges, and broadleaf weeds like shamrock, crabgrass, green foxtail, velvetleaf, mallow, mustard, purslane, and field bindweed.
For best results, apply DuPont Baocheng when tomato plants reach about 30 cm in height. Dilute the herbicide and spray it at a rate of 6,000 to 8,000 times. This method ensures that the herbicide effectively kills the weeds while remaining safe for the tomato plants. During application, the sprayer should be positioned below the growth point of the tomato plants, ensuring even coverage between the rows without directly spraying the leaves or stems.
It's important to avoid using organophosphate insecticides within seven days before or after applying the herbicide, as this can cause phytotoxicity and damage the crop. Proper timing and technique are key to successfully managing these stubborn weeds without harming the valuable tomato plants.
