Huge yield losses and deterioration of quality of cultivated plants occur due to continuous exposure of plants to pathogens and insect pests. The excessive use of chemical pesticides and fertilizers in modern agriculture result in a deterioration of soil fertility and through intracellular accumulation pesticide-resistant mutants of insects and plant pathogens have emerged worldwide. A number o...

Western flower thrips (Frankliniella occidentalis) has become a key insect pest of agricultural and horticultural crops worldwide. Little is known about host plant resistance to thrips. In this study, we investigated thrips resistance in chrysanthemum (Dendranthema grandiflora). We identified thrips-resistant chrysanthemums applying bioassays. Subsequently, nuclear magnetic resonance (NMR)-base...

To date, only bar/pat gene derived from Streptomyces has been used to generate the commercial PPT-resistant crops currently available in the market. The limited source of bar/pat gene is probably what has caused the decrease in PPT-tolerance, which has become the main concern of those involved in field management programs. Although glutamine synthetase (GS) is the target enzyme of PPT, little s...

The article presents the effect of different insertion buckwheat as a catch crop on weediness spring barley and bean crops. research was carried out in 2019–2020 at farm Virmantas Pocius, located Pakruojis District, two fields, near Draudeliai Village. experiment variants were following: 1) tillage cover crops autumn (control); 2) shallow to depth 5 cm autumn; 3) deep 20 autumn. In control crop...

variety of crops. Pot tests indicated that addition of about 200 p.p.m. of copper from copper sulfate produced a toxic reaction in soils low in copper, but otherwise comparable to Alsatian vineyard soils, which were found to contain as much as 400 p.p.m. of copper. Among the crops tested, vines were most resistant to copper toxicity; clover and alfalfa were most sensitive. Symptoms of copper po...

The present study aims to recognize dhow prawn trawl by-catch from Hormuzgan coastal waters (Northeast Persian Gulf). Sampling was carried out of 36 hauls by using traditionally wooden dhow among prawn fishing season in 2011. The catch composition consisted of 31.66% target species prawns, mainly banana prawn (Penaeus merguiensis) and 68.34% by-catch. The total by-catch was 4,622.67kg com...

Food losses in field and store 5 cause outstanding losses in many crops. Because there are few trained nematologists, many other important nematode problems on key food crops such as rice and paddy remain uninvestigated. Because nematodes are soil organisms, control is especially difficult. Few satisfactory nematicides are known and these are too expensive for most agricultural crops in Europe....

Abstract Herbicide-resistant (HR) crops are widely grown throughout the United States and Canada. These crop-trait technologies can enhance weed management therefore be an important component of integrated (IWM) programs. Concomitantly, evolution HR populations has become ubiquitous in agricultural areas where grown. Nevertheless, crop cultivars with new or combined (stacked) traits continue to...
