When it number to control dark-brown temporary hookup , there are several fungicides that can be effective . However , it ’s significant to note that the duration of control condition may depart look on the specific product used . Three antimycotic agent that provide longer - endure control for up to 28 days are azoxystrobin , pyraclostrobin , and fluoxastrobin . On the other hand , there are three other fungicide that propose control for 14 solar day . Let ’s take a closelipped expression at these options .
1 . Azoxystrobin : This fungicide has try out to be effective in controlling brown patch for up to 28 day . It forge by inhibiting respiration in the fungal cells , finally leading to their death . I have personally used azoxystrobin in my own garden and have take in capital effect in controlling chocolate-brown patch . The key is to watch the label program line carefully and give it at the recommend rate .
2 . Pyraclostrobin : Similar to azoxystrobin , pyraclostrobin is another fungicide that provides 28 - day control . It belong to the same grade of chemicals known as strobilurins . In my experience , pyraclostrobin has been effective in controlling brown dapple , and it also has a preventive natural process against other turf diseases . However , it ’s important to note that restate use of strobilurin fungicides can lead to the development of resistance in the pathogen universe , so it ’s advisable to revolve fungicides with different modes of natural process .
3 . Fluoxastrobin : Another antimycotic that offer 28 - day control is fluoxastrobin . It works by break up the energy production in the fungal cells , lead to their demise . I have not in person used fluoxastrobin , but I have discover positive feedback from fellow gardeners who have successfully ascertain brown plot with this product . As with any antifungal , it ’s crucial to adopt the label instructions and practice it correctly .
In increase to these longer - hold out options , there are three other antifungal agent that provide ascendency for 14 days :
4 . Propiconazole : This antifungal belongs to the class of chemicals know as demethylation inhibitors ( DMIs ) . It works by step in with the deduction of ergosterol , a vital component of fungal cell membranes . Propiconazole has been wide used for brown patch control and has shown good efficaciousness . However , it ’s worth noting that repeated applications of DMIs can also take to the development of electric resistance , so it ’s important to rotate fungicides with different modes of action .
5 . Myclobutanil : Another DMI fungicide , myclobutanil , can provide restraint for 14 days . It work in a similar way to propiconazole , inhibiting ergosterol synthesis . I have used myclobutanil in the yesteryear for other turf diseases , and it has proven to be effective . However , it ’s of import to take note that myclobutanil has a higher risk of resistance development compared to propiconazole , so right rotary motion is essential .
6 . Chlorothalonil : This multi - site tangency fungicide is also efficacious against browned patch and provide control for 14 days . Chlorothalonil work by interfere with various metabolic appendage in the fungous cellphone , ultimately leading to their death . I have used chlorothalonil in my garden for various fungal diseases , and it has always delivered good results . It ’s crucial to observe that chlorothalonil has a low risk of exposure of resistance growing , making it a valuable tool in disease management .
It ’s worth mention that right ethnical practices , such as mowing at the right height , avoiding inordinate atomic number 7 fertilisation , and improving soil drain , are lively in preclude and contend dark-brown patch . Fungicides should be used as part of an integrated approaching that include these cultural practice to reach the best results .
When it come up to command brown patch , antifungal agent such as azoxystrobin , pyraclostrobin , and fluoxastrobin offer longer - lasting control condition for up to 28 years . antimycotic agent like propiconazole , myclobutanil , and chlorothalonil offer dominance for 14 days . The choice of antimycotic agent will bet on factors such as the severity of the disease , the want continuance of control , and the potential for opposition development . It ’s always important to carefully say and follow the recording label instructions when using fungicides and to rotate mathematical product with unlike mode of activeness to prevent resistance .
