A new type of sulfonylurea herbicide, developed by the nissan chemical company, is an inhibitor of the acetyllactic acid synthase (ALS).Namely by inhibiting plant ALS enzyme, stop the branched chain amino acids, such as valine, isoleucine, leucine, biosynthesis, eventually destroy the protein synthesis, DNA synthesis and cell division and growth.It can be absorbed through the roots, stems and leaves of plants.The symptoms of weed control include cessation of growth, loss of green, apical meristem death, and plant death after 2 ~ 3 weeks.Widely used in wheat, corn, rice, sugar cane, lawn crops, such as main control broadleaf weeds and cyperaceae weeds such as abutilon, xanthium sibiricum, mandala, ratchet, ragweed and trifid leaf ragweed, v, wild sunflowers, amaranthus retroflexus, wild watermelon seedlings, sorrel smartweed, willow leaves thorn smartweed, purslane, morel, cassia occidentalis, petunia, cyperus rotundus, iron water chestnut, chufa, etc.Because of its rapid metabolism in crops as harmless, crop safety.It can be used before and after seedling.In addition, its toxicity to human body and fish is very low, there is no "three".
1. Application of clopidosulfuron in the application of crops:
1. Application in rice:
The rice herbicide Permit(clopidosulfuron) was developed by nissan chemical Europe, a subsidiary of Japan's nissan chemical co., and has been approved in Italy.The recommended dosage of this product is 30 ~ 50 g/ha.This product has established a good reputation in the Japanese rice market.It has also been sold on corn, sugar cane and other crops in north and South America.
2. Application on corn:
Active ingredients in the use of doses for chloride under 35 g/ha pyrazole its cycling for common weeds in corn field xanthium sibiricum, duck plantar grass, amaranthus retroflexus, cyperus rotundus, etc the fresh weight of inhibition rate were above 90% but smoke on basic invalid and gramineous weeds and contrast agents, its great complementarity cycling.Chlorine pyrazole its cycling differences on security in 23 different corn varieties significantly, under the active ingredients of 140 g/ha, feeding 18, five varieties of jade, 7 mountains is relatively sensitive, plant height inhibition rate were above 9.85%;The sensitivity of 12 cultivars, such as jinhai 5 and lushan 981, was slightly lower, with a high inhibition rate of 4.31%~8.29%.The resistance of 6 varieties, such as zhengdan 958 and tai-bang 1, was relatively high, and the inhibition effect was not obvious.Chlorine pyrazole its cycling of corn seedling root long inhibition rate is put in bigger difference, the IC50 alue concentration from high to low in turn stronger explosion of pt 1, 16, zheng single 958, nongda 108, 21, 981, lu yue yu, sea, 5, 9, nongda 0638, sweet corn.The selectivity coefficient of clopidosulfuron was 16.11 and 13.18, respectively, between corn and acanthopanax and amaranth.
In conclusion, clopidosulfuron has high herbicidal activity in some common broad-leaved weeds and sedge weeds in the corn field, and is safe for most maize varieties, and has a good prospect in promotion and application.The corn field herbicide should be used with the antidote MON13900.During the 3-5 leaf stage of the corn seedlings, the period of 3-5 leaves of the weed, the best period of 4-5 leaves were administered once.The dosage is 75% wdg45-60g/ha and 15-30 litres of water.Corn fields can be mixed with sulfur-sulfuron, fluorapsulfuron, atrazine, bromobenzene, tachyprin, and trisulfamide.The maize seedlings were not recommended to be mixed with 2, 4- drops and 2 - a - 4 chlorine.
3. Application in sorghum:
2-4 leaves of the sorghum seedlings before the ear of the ear.Dosage: 50%WP 72 ~ 140g (active ingredient 36 ~ 70g)/ha.The sorghum field can be mixed with atrazine, bromobenzene, wheat grass and disulfamide.
4. Application on tomatoes:
Clopidosulfuron can also be used in tomato growing season.According to the test ya-lin sun vegetable science institute in wuhan city, hubei province, were chloride pyrazole its cycling of tomato fields, cyperus rotundus, wild amaranth, pine nuts, iron amaranth broadleaf weeds and sedge control effect is good and lasting effect.In tomatoes, weed 2 ~ 4 leaf stage after transplanting, chloride with 75% per acre pyrazole its cycling WDG4 30 kg ~ 12 grams, add water spray, 60 days of cyperus rotundus, wild amaranth, pine nut and iron amaranth plant control effect and the overall plant control effect were held at 84.86% ~ 97.76%, 82.72% ~ 95.44% and 82.72% ~ 90.16%, 71.85% ~ 90.18% and 82.52% ~ 90.18%;The fresh weight and the total fresh weight protection were 86.06% ~ 98.29%, 84.73% ~ 97.05%, 79.91% ~93.25%, 76.2%~93% and 83.53%~96.09%, and the fresh weight control effect and strain protection were significantly better than that of artificial weeding.With the increase of the amount of medicine, the effect of weed control was improved.Comprehensive consideration was given to the use of 75% clopidosulfuron-wdg sprays in the tomato field, which was recommended for 4-8 grams per acre.
5. Application on spring wheat:
It is recommended to use 75% chlorine pyrazole its cycling WDG usage is 75 ~ 75 g/ha (effective composition content of 56.25 ~ 67.5 g/ha) in spring wheat phase 3 ~ 5 leaves cauline leaf spray, for the Chinese mosla herb, thin purusha, quinoa, malva grass weeds were can reach more than 80%.
6. Application on sweet potatoes:
75% chlorine pyrazole its cycling WDG for GongShuTian broadleaf weeds and cyperus rotundus, cyperaceae weeds have very good control effect, high on the safety of sweet potato, has no effect on sweet potato production, to achieve a certain effect to increase production.Therefore, can be used in GongShuTian chlorine pyrazole its cycling, were suggested in 2 ~ 4 weed leaf stage spray processing, from the comprehensive effect and drug costs, recommend the effective composition content of 45 ~ 60 grams/ha.Due to the large diversity of weeds in different regions and different planting conditions, further experiments should be conducted to further observe the effects of various crops on the next crop, and then to promote and use them.
7. Application on sugarcane:
Chlorine pyrazole its cycling is the only safe to sugar cane and eradicate sugarcane field of rhizoma cyperi miao miao before after herbicide, main characteristic is low dosage, high efficacy, has special effects to the broadleaf grass and cyperaceae weeds, 75% chlorine pyrazole its cycling WDG in sugarcane field using optimum period is:
1) closed treatment of seedlings: before the seedling of sugarcane planting, the soil layer was kept moist and recommended dosage of 6-8 grams of water 60 to 90 jin of water per mu for soil treatment.
2) after the seedling treatment: in the sugarcane field, 7-11 leaves were used 75% wdg10-15g with a water spray of 120-180 kg, with the best effect.
8. Application on the lawn:
According to the report, bayer crop science was used in the United States to promote a blend of lawn herbicide Tribute Total(ketone urea), which was approved by the United States.The Tribute Total is a new type of herbicide with broad spectrum weeding, which helps the lawn and golf course manager selectively remove certain grasses and broad-leaved weeds, such as sedge.Unique mixed reagent mix a variety of products from trouble, for weed control provides a complete solution, and don't need to make barrels to mix a variety of products, saving time and cost.The Tribute Total had previously been approved for Bermuda grass.The product is effective for 55 gramineae and broadleaf weeds, including madon, yellow and purple sedge.The contribution of the Tribute Total is 60.5%WDG with a standard of 1-3.2 ounces per acre, and the package contains 6 ounces per container, which can be applied to 1.875-6 acres.
