However, Quizalofop-P can be used to kill weeds in the current crop field and will not affect subsequent crops because it does not cause soil residue problems. This is something you can rest assured.
Quizalofop-P (94051-08-8) herbicide uses
The herbicide Quizalofop-P is a phenoxy fatty acid herbicide, a selective systemic conductive stem and leaf treatment agent. The pesticide is highly selective between grass weeds and dicotyledonous crops. The stems and leaves can complete the absorption of the pesticide within a few hours, and annual weeds can spread throughout the entire plant within 24 hours. It is suitable for controlling monocotyledonous weeds in cotton, soybeans, rapeseed, peanuts, flax, apples, grapes, sugar beets and a variety of broad-leaf vegetable crops. When the dosage is increased, it is also effective against perennial weeds such as bermudagrass, cogongrass, and reed. For example, to control grassy weeds in cotton fields, apply pesticides at the 3 to 5 leaf stage. Use 10% EC 7.5 to 10.5 mL/100m2 and spray the water stems and leaves; to control annual grass weeds in soybean fields, apply pesticides at the 3 to 5 leaf stage. , use 10% EC 9 ~ 15mL/100m2, spray 6 ~ 7.5kg of water evenly; to control wheatgrass in rape fields, use the medicine when the weeds are out and are leafing out or there is one leaf. Use 10% EC 5.3 ~ 7.5mL/100m2; to control grassy weeds at the 4-6 leaf stage, use 10% EC 20-30mL/100m2.

How to use Quizalofop-P (94051-08-8) herbicide
The herbicide Quizalofop-P is mainly used in soybeans, cotton, peanuts, sugar beets, tomatoes, cabbage, grapes and other crop fields to control barnyardgrass, crabgrass, goosegrass, wheatgrass, foxtail grass, wild oats, bermudagrass, and reeds. , Imperata cognac and other annual and perennial grassy weeds. To control annual grass weeds, when the weeds have 3-6 leaves, use 40-60 ml of 5% EC per acre and 40-50 kg of water for stem and leaf spray treatment. To control perennial grass weeds, when the weeds have 4-6 leaves, use 130-200 ml of 5% EC per acre and 40-50 kg of water for stem and leaf spray treatment.
The herbicide Quizalofop-P can spread throughout the entire plant within 24 hours, causing necrosis of annual weeds. After annual weeds are treated with pesticides, new leaves turn yellow and stop growing in 2-3 days, stems and leaves become necrotic in 4-7 days, and the entire plant dies within 10 days. After perennial weeds are treated with pesticides, the pesticides are rapidly transmitted to underground rhizome tissues, causing them to lose their ability to regenerate.
The control effect of grass weeds is best at the 3-5 leaf stage. To control annual grass weeds, use 20-40ml of 10% Quizalofop-P EC per bucket of water.
When the weather is dry or the weeds are large, the dosage of pesticides needs to be increased appropriately.
1. Quizalofop-P in the nursery: Pay attention to avoid seedlings when spraying, and spray to control weeds when they have 3-5 leaves.
2. The use of Quizalofop-P in cotton and peanut fields: Generally, after the emergence of cotton, when the grassy weeds grow to 3-5 leaves, spray Quizalofop-P evenly to control the grassy weeds.
3. Cabbage, watermelon, sesame, etc.: After crop emergence, when the annual grassy weeds grow to 3-5 leaves, spray Quizalofop-P. If it is close to wheat and corn, be careful that drifting harms wheat and corn. Do not spray when there is wind; wear a spray hood when spraying and lower the nozzle to spray.
4. When soybeans are in the 3-5 leaf stage of annual grass weeds and soybeans have 1-3 compound leaves, use 0.75-1.2 liters of 5% EC per hectare and 450 liters of water (50-80 ml per acre and 30 liters of water). Knapsack sprayer, fan-shaped nozzle for uniform spraying of stems and leaves. To control perennial grassy weeds mainly reeds, the dosage per hectare should be increased. Use 2-2.5 liters of 5% EC per hectare, and add 200-300 liters of water (133-200 ml per acre, add 13-20 liters of water). Spray the stems and leaves evenly at the 4-6 leaf stage.
5. When cotton is in the 3-4 leaf stage of cotton seedlings and annual grass weeds are in the 3-5 leaf stage, use 0.75-1.0 liters of 5% EC per hectare and 300 liters of water (50-67 ml per acre, add 20 liters of water). Stem and leaf spray treatment.
6. To control gramineous weeds, mainly sedge, in rapeseed, apply the pesticide when the sedge appears and is in the early stage of tillering. Use 0.6-0.9 liters of 55 EC per hectare and add 450 liters of water (40-60 ml per acre, Add 30 liters of water) to spray the stems and leaves.
7. To control grassy weeds, mainly crabgrass and barnyardgrass, with peanuts, use 0.75-1.0 liters of 5% EC per hectare, add 450 liters of water (50-67 ml per acre, add 30 liters of water), and remove 3-3 liters of weeds. At the 5-leaf stage, spray treatment on stems and leaves.
The difference between Quizalofop-P (94051-08-8) and Flumefofop
1. Reed removal: Flufenopyfen is much more effective. Within a height of 1000px, 60ml is enough, and above 1000px, 80ml is enough. The essence should be no less than 90ml, and most require 120ml. Within 1000px, no matter how high it is, the effect will be difficult to guarantee.
2. Low-temperature effect: The low-temperature effect of flufenofop is much better. The above effect shows that Quizalofop-P is greatly affected by temperature, and is not very effective on older grasses, and the absorption speed is relatively slow. However, flumefenofop-op is relatively unaffected by temperature, especially The influence of low temperature,
3. Weeds are in season. When monocotyledonous weeds have 2-4 leaves, the effect of Esquine is good. However, if the weeds are slightly older, the effect of Esquine will not be able to keep up, and it will not work if the dosage is increased. It is not easy for farmers to control the time of medication. It has been promoted for so many years and farmers all know it. Adding fluopyfenethofop has no problem with the effect.
4. For those who understand technology, Jingquin is cost-effective; for those who do not understand technology, it is safer to use flufenofop. Basically control the entire growth period and grass damage. The drug dissolves in the soil and has no effect on crops.
This concludes the introduction of the difference between Quizalofop-P and Flumefop. Flumefop has a good control effect on annual and perennial grasses from post-emergence to tillering and early heading stages. Not effective on broadleaf grasses and sedges. For broad-leaf crops, the efficacy is long, and one application can basically control the entire growth period and grass damage. The drug dissolves in the soil and has no effect on crops.
Precautions for Quizalofop-P (94051-08-8) herbicide
1. When using Jinglong Tianling to control foxtail grass, Ye Tai should use 0.75-1.0 liters per hectare. The dosage needs to be adjusted according to the leaf age of the weeds. The dosage can be lower for weeds with younger leaves, and the dosage should be appropriately increased for weeds with older leaves.
2. Mixing with bentazone will reduce the stele-killing effect of Jingfengheling, and it cannot be mixed with triflufen and mesobutyric acid.
3. After applying the pesticide on the leaves of the weeds, the weed plants will turn yellow and stop growing within 2 days. 5 to 7 days after the pesticide application, the young leaves and primary tissues on the nodes will wither, and the weeds will die completely in about 14 days. .
4. It can only be used once for annual weeds such as cotton, peanuts, rapeseed, and soybeans.
5. Wear mouthpieces and rubber gloves when operating. After the operation, wash your face, hands, and feet with soap, and rinse your mouth with water.
6. If you drink by mistake, drink plenty of water, spit out the liquid, and seek medical attention immediately to take rescue measures after calming down.
7. It is sensitive to grass crops. When spraying, do not spray adjacent rice, corn, barley, wheat and other grass crops to avoid phytotoxicity.
8. The spray should be even and the entire weed plant should be sprayed. If rain occurs within 2 hours after spraying, it will have little effect on the efficacy, so there is no need to spray again.
9. When the soil is dry, the dosage can be appropriately increased.
10. Under dry weather conditions, phytotoxicity may sometimes occur on the leaves of crops, but there will be no phytotoxicity on new leaves and no impact on yield.
