Description
DINOBUTON is a non-systemic fungicide that is effective in controlling powdery mildews in various crops such as apples, cotton, and vegetables. It works by inhibiting the growth and development of fungal pathogens, thereby protecting the plants from diseases and ensuring a healthy yield.
Uses
Used in Agriculture:
DINOBUTON is used as a fungicide for the control of powdery mildews in various crops. It is particularly effective in protecting apples, cotton, and vegetables from fungal infections, ensuring a healthy and bountiful harvest.
Used in Apple Production:
DINOBUTON is used as a protective agent in apple production, targeting powdery mildews that can cause significant damage to the fruit and reduce crop yields. By applying DINOBUTON, farmers can effectively manage these fungal infections and maintain the quality and quantity of their apple harvest.
Used in Cotton Production:
In the cotton industry, DINOBUTON serves as a crucial fungicide to combat powdery mildews that can negatively impact the growth and quality of cotton plants. Its application helps in safeguarding the cotton crop from diseases, leading to improved fiber production and overall crop health.
Used in Vegetable Production:
DINOBUTON is also utilized in vegetable production to protect plants from powdery mildews that can affect their growth and yield. By incorporating DINOBUTON into their disease management strategies, farmers can ensure a healthy and productive vegetable crop, contributing to a stable food supply.
Metabolic pathway
Dinobuton is metabolised in plants and animals via common metabolic
pathways. The primary reaction is hydrolytic cleavage of the
carbonate-dinitrophenyl linkage to yield dinoseb. Further reduction of
the nitro-groups of dinoseb yields the corresponding monoamino and
diamino analogues. Acetylation and deamination via hydroxylation/
elimination, and oxidation of the sec-butyl moiety also occurred. N- and
O-Conjugation as glucosides and glucuronides occurred in both plants
and animals. The metabolic pathways of dinobuton are presented in
Scheme 1.
Degradation
There is limited information on the hydrolytic stability of dinobuton (1).
Marchenko and Vakulenko (1983) reported that the hydrolysis DT50 values
of dinobuton in pH 2, 7 and 11 buffer solutions at 22 °C were 15 days,
17 days and 4 hours, respectively. In vitro studies showed the rapid
hydrolysis of dinobuton to dinoseb [ 2-sec-butyl-4,6-dinitrophenol (2)] by
tissue homogenates of spider mites and animal tissues. Once generated,
dinoseb was stable to hydrolytic and photolytic degradation under acidic
condition but was readily degraded under alkaline conditions (Brestkin
et al., 1978; Molnar, 1935). Uncharacterised complex polar materials
were reported as photodecomposition products of dinoseb (Matsuo and
Casida, 1970). Grechko et al. (1986) reported that the DTW for dinobuton
in aqueous solution under UV light irradiation (365 nm) was <30 min.
Check Digit Verification of cas no
The CAS Registry Mumber 973-21-7 includes 6 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 3 digits, 9,7 and 3 respectively; the second part has 2 digits, 2 and 1 respectively.
Calculate Digit Verification of CAS Registry Number 973-21:
(5*9)+(4*7)+(3*3)+(2*2)+(1*1)=87
87 % 10 = 7
So 973-21-7 is a valid CAS Registry Number.
