Triazine resistant Echinochloa colona (junglerice) in Iran
The most common mechanism of resistance to triazine herbicides is a mutation in the psbA gene, which encodes the 01 protein, leading to an alteration at the site of the protein where triazine binding occurs. Suspected resistant Echinochloa colona...
A field study on the effects of the herbicide Tribenuron methyl on biodiversity of wheat aphids (Homoptera:
To identify the impacts of chemical control of weeds on wheat aphids community, a field experiment was conducted in a completely randomized design with two factors, each in three replicates in a 20-ha wheat field.
The herbicide treatment...
Effects of a magnetic field and adjuvant in the
The reduction of herbicide applications is a main research priority in recent years. One way to
achieve this goal is by using adjuvants that can increase the efficacy of foliar-applied herbicides
by reducing surface tension. Previous...
Response of aphidophagous hoverflies (Diptera, syrphidae) to herbicide in winter wheat
The primary approach used for reducing weeds in wheat fields is the application of broadleaf-selective herbicides, which could have important implications for the arthropod community in this crop. the objective of this study was to identify...
Allelopathic Potential of Lavender’s Extract and Coumarin Applied as Pre-Plant Incorporated Into Soil Under Agronomic Conditions
This study aimed to further explore that if coumarin and lavender’s
extract, similar to greenhouse conditions, are phytotoxic towards some plant species
under agronomic conditions. Before planting of maize, coumarin ...
Activity of the Recommended and Optimized Rates of Pyridate on Chickpea - Mesorhizobium mediterraneum Symbiosis
Crop-rhizobium symbiosis can be influenced by leaching of herbicides which is unavoidable after their application. Due to an adjuvant which might help to develop the low-use-rate of herbicide, an experiment was carried out to compare the impact...
Overcoming Hard Water Antagonistic to Glyphosate or Imazethapyr with Water Conditioners
Carrier water quality may affect the activity of weak acid herbicides when concentrations of some cations are high. A doseresponse experiment on glyphosate and imazethapyr activity, which were carried by the carrier types of distilled water and hard...
Photochemical Behavior of Sethoxydim in the Presence of Vegetable Oils
The photodecomposition of herbicides may be affected by adding vegetable oils to the spray tank. In this study nine vegetable oils were compared to assess the photodecomposition of sethoxydim under natural light conditions. The experiment...
Optimizing Sulfosulfuron and combination of Sulfosulfuron Metsulfuron-methyl Activity Tank-Mixed with Vegetable Oil to Control Wild Barley(Hordeum spontaneum Koch.)
Newly developed herbicides such assulfosulfuron or sulfosulfuron plus metsulfuron-methyl may control wild barly at higher rate than recommended dose. But causing significant wheat injury. Hence, two dose-response experiments were conducted...
Confirmed resistance to aryloxyphenoxypropionate herbicides in Phalaris minor populations in Iran
Phalaris minor (littleseed canary grass) is a major weed in wheat fields in some parts of Iran.
Diclofop-methyl, fenoxaprop-P-ethyl, and clodinafop-propargyl are three acetyl coenzyme A
carboxylase (ACCase)-inhibiting herbicides...
