Primisulfuron-methyl is a synthetic herbicide belonging to the sulfonylurea class of compounds. It is characterized by its ability to inhibit acetolactate synthase (ALS) in plants, which is a key enzyme in the biosynthesis of branched-chain amino acids. This action leads to the cessation of plant growth and eventually results in plant death. Primisulfuron-methyl is highly selective and effective against a broad spectrum of broadleaf and grass weeds.
Used in Agriculture:
Primisulfuron-methyl is used as a herbicide for weed control in various crops such as corn, sugarcane, and cereals. It is applied pre-emergence or post-emergence to control a wide range of broadleaf and grassy weeds, thereby reducing competition for resources and promoting healthy crop growth.
Used in Pesticide Formulations:
Primisulfuron-methyl is also used as an active ingredient in various pesticide formulations, which are specifically designed for targeted weed control in different agricultural settings. These formulations may include different concentrations and combinations with other herbicides or pesticides to enhance their effectiveness and broaden their weed control spectrum.
Used in Integrated Pest Management (IPM) Programs:
Primisulfuron-methyl can be incorporated into integrated pest management (IPM) programs, where it is used in combination with other pest control methods such as cultural practices, biological control, and mechanical control. This approach helps to reduce the reliance on chemical pesticides and promotes sustainable agriculture by minimizing the environmental impact and potential resistance development in weeds.

Check Digit Verification of cas no

The CAS Registry Mumber 86209-51-0 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 8,6,2,0 and 9 respectively; the second part has 2 digits, 5 and 1 respectively.
Calculate Digit Verification of CAS Registry Number 86209-51:
(7*8)+(6*6)+(5*2)+(4*0)+(3*9)+(2*5)+(1*1)=140
140 % 10 = 0
So 86209-51-0 is a valid CAS Registry Number.

Soybean plants with dominant selectable trait for herbicide resistance

-

, (2008/06/13)

The utilization of a positive selection seed screening process to isolate rate variants with resistance to a herbicide is described. The ability to screen large numbers of mutagenized seed has made it feasible to pursue and isolate plants with low frequency dominant herbicide-resistance mutations. The dominant herbicide resistance mutations are useful for many applications including expanding the utility of sulfonylurea herbicides for soybean weed control, production of F1 and F2 seeds, and as selectable markers for efficient seed purification.
