Suppression of hop looper (Lepidoptera: Noctuidae) by the fungicide pyraclostrobin.
The hop looper, Hypena humuli Harris, is a reemergent pest of hop that often requires treatment to mitigate crop damage. In 4 yr of field trials, plots treated with fungicides were observed to sustain less hop looper defoliation compared with nontreated plots. Further investigation revealed that abundance of hop looper and associated defoliation were reduced when the fungicide pyraclostrobin wa...
متن کاملBioefficacy of Pyraclostrobin 25%EC Against Early Blight of Tomato
Pyraclostrobin 25%EC at., 50, 75 and 100ga.i/ha, was evaluated for two seasons against early blight of tomato cultivar NS2535. The efficacy of pyraclostrobin was compared with commonly used chemicals viz., captan, mancozeb and an untreated control. Phytotoxicity effect of pyraclostrobin was evaluated using a single spray, at concentrations of 100, 200 and 400gm a.i/ha Pyraclostrobin at all conc...
متن کاملResistance to Phosphite Fungicide
There are a number of turf fungicides the activity of which is based on the phosphite (=phosphonate) ion (P03-). Chipco Signature fungicide (active ingredient fosetyl-Al) is the most common, and has become a "keystone" product for disease control programs on many golf courses across the country. This is in part because of the general enhancement in quality on stressed turfgrass that has been re...
متن کاملEffect of Host Plant Resistance and Reduced Rates and Frequencies of Fungicide Application to Control Potato Late Blight
Late blight of potato (Solanum tuberosum, L.) caused by Phytophthora infestans (Mont.) de Bary, is a major worldwide threat to the production of high quality potatoes (12). Unchecked, P. infestans can rapidly defoliate plants in the field and can infect potato tubers when spores are washed into the soil (15). Prior to the early 1990s, the population of P. infestans throughout much of the world ...
متن کاملEvaluation of Resistance to Zymoseptoria tritici Blotch andFusarium Head Blight in Some Genotypes of Bread Wheat
Using resistant cultivars is an effective method in management Zymoseptoria tritici Blotch and Fusarium Head Blight of wheat. This study was conducted to identify new sources of resistance to these diseases among a large number of Iranian cultivars and new wheat genotypes. The genotypes were cultivated in an augment design in the research farm of Aliabad Katoul Agricultural School. Artificial c...
