Currently, most of glufosinate-ammonium products on the market cannot completely kill goosegrass herb. During the regrowth of goosegrass herb, it needs to absorb more soil moisture and nutrients, and its roots will further grow deeper and thicker, sprouting more fibrous roots. If goosegrass herb cannot be completely killed, they will grow larger and deeper, produce more seeds when mature. Moreover, applying glyphosate alone to prevent and control goosegrass herb is almost ineffective once it has developed resistance to glyphosate.
In many vegetable growing areas, glufosinate-ammonium has been used for inter-row weeding for a long time. However, now only goosegrass herb remains uncontrolled, and even glufosinate-ammonium and glufosinate-p cannot kill it.
In some areas where nursery stocks are planted, in order to maintain soil and air humidity for seedling growth, they need to be watered every two to three days. The frequent watering dilutes and detoxifies the effects of glufosinate-ammonium, resulting in a rapid increase in goosegrass herb's resistance to glufosinate-ammonium in local tree nurseries. Currently, the dosage of 400g glufosinate-ammonium per bucket(15~20L) of water is basically ineffective for controlling goosegrass herb.
So, is there really no way to control resistant goosegrass herb and other malignant grassy weeds?
Juqida (Glufosinate-ammonium 60% + Flumioxazin 6% WP)
The active ingredient Glufosinate-ammonium of Juqida, it inhibits the synthesis of glutamic acid synthetase, causing nitrogen metabolism disorder in weeds, resulting in excessive accumulation of ammonium ions and causing chlorophyll to break down, thus inhibiting photosynthesis. Flumioxazin can form a film on the soil surface, which has a dual-effect of killing and preventing, effectively controlling annual broadleaf weeds and some grassy weeds. It is easily degraded in the environment and is safe for the afterreap crop.
Product features:
1. A combination formulation for a broad spectrum of weed control.
2. Low temperature resistance, and with stable efficacy in low temperatures.
3. Not limited to sunlight conditions, with guaranteed efficacy on cloudy and rainy days.
4. Dual contact killing and systemic action for comprehensive and thorough weed control.
Application techniques:
1. Dilute 25g of this product with 15L water, spray evenly and directionally. The efficacy is more thorough with sufficient sunlight.
2. The best efficacy is achieved when the soil surface is moist but there is no surface water and when there is sufficient sunlight. It is recommended to spray the leaves of weeds from the time when the dew on the leaves disappears in the morning until noon, and from the time when the temperature drops in the evening until dark.
3. Avoid applying the herbicide during hot afternoons in the summer. When there is a lot of dust on the surface of the weeds, it is recommended to first rinse them with water before spraying.
