چکیده به منظور بررسی کارایی چهار علف کش اتال فلورالین، تریفلورالین، پندیمتالین و متری بوزین در مزارع سیب زمینی و روی علف های هرز سلمه و تاج خروس آزمایشی گلخانه ای در سال 1387 در دانشگاه محقق اردبیلی انجام شد. آزمایش ها به صورت پاسخ به دز در قالب طرح کاملاً تصادفی با 4 تکرار و با استفاده از رقم آگریا انجام شد. کلیه علف کش ها در 6 دز به صورت دزهای کاهش یافته تا دزهای افزایشی نسبت به دز توصیه شده ا...

abstractgrowth of b. japonicum isolates at different concentrations of herbicide used on soybean was studied as factorial experiment arranged in a completely randomized design with three replications. isolates b1, b6, b43 and 0, 0.125, 0.25, 0.5, 1, 2, 4, 8 and 16 folded of the recommended doses of trifluralin, metribuzin and imazethapyr herbicides were considered as factors. isolates populatio...

The effects of nematicides carbofuran (C) and fenamiphos (F) and herbicides metribuzin (M) and trifluralin (T), alone and in combination, on hatching, penetration, development, and reproduction of Meloidogyne incognita race 3 were determined under laboratory conditions. To study hatching, entire egg masses were exposed to nematicides (6 mug/ml), herbicides (0.5 mug/ml), and their combinations o...

Residues of the herbicides simazine, metribuzin, metolachlor, trifluralin, atrazine, and two metabolites of atrazine, deisopropylatrazine (DIA) and deethylatrazine (DEA), are surveyed in the surface and groundwater of the Primavera do Leste region, Mato Grosso, Brazil during September and December 1998 and April 1999. Different water source sampling stations of groundwater (irrigation water wel...

Historic and current use pesticides (HUPs and CUPs), with respect to use in the United States and Canada, were identified in trans-Pacific and regional air masses at Mt. Bachelor Observatory (MBO), a remote high elevation mountain in Oregon's Cascade Range located in the United States, during the sampling period of April 2004 to May 2006 (n = 69), including NASA's INTEX-B campaign (spring 2006)...

The dinitroaniline herbicides (particularly trifluralin) have been globally used in many crops for selective grass weed control. Consequently, trifluralin resistance has been documented in several important crop weed species and has recently reached a level of concern in Australian Lolium rigidum populations. Here, we report novel mutations in the L. rigidum α-tubulin gene which confer resistan...

Herbicide, Inhibition, Photosynthetic Electron Transport, Trifluralin, Thermoluminescence The effect of trifluralin on the photosynthetic electron transport has been investigated by oxygen evolution and thermoluminescence measurements. The results confirm the earlier observations that trifluralin at low concentrations blocks electron transport between the two photosystems probably at the same s...
