Prime editing is a novel and universal CRISPR/Cas-derived precision genome-editing technology that has been recently developed. However, low efficiency of prime editing has been shown in transgenic rice lines. We hypothesize that enhancing pegRNA expression could improve prime-editing efficiency.

In the present study the nanocapsulation of Haloxyfop-R-methyl in poly(methyl methacrylate) was successfully performed. Poly(methyl methacrylate)/Haloxyfop-R-methyl nanocapsules were synthesized using a miniemulsion method and their surface morphology was studied by scanning electron microscopy and transition electron microscopy. The chemical characterization of nanocapsules was done by FT-IR spectroscopy. The herbicide loading and encapsulation efficiency were also analyzed for the herbicide-loaded nanocapsules.

Photocatalytic degradation of the herbicide quinclorac in water using Mn (III) salen and solar light
Quinclorac (QNC) is a widely used herbicide and is persistent in surface and ground waters. Its residuals and converted products are hazardous to aquatic animals, vegetation, and microbes, and it is therefore important to degrade QNC using an efficient and environmental friendly technology.

This study was taken to know the weed control efficiency of herbicides in chickpea intercropping with lentil. The weed competition was highest during 30 DAS and the maximum weed density was found in 60 and 90 DAS. Weed species were recorded such as broadleaf weeds like Coronopus didymus, Chenopodium album, Melilotus officinalis, Phalaris minor, etc. The main focus of this experiment was to study dry matter accumulation by weeds at different days after sowing (30, 60, 90, and 120).

Therefore, it is necessary, to find out the alternative methods for reducing the weed load during early growth period of soybean to get economical yields. Thus, herbicidal weed control remains only the choice under such situation to minimize the weed menace economically. Therefore, keeping the above facts in view, the present experiment has been carried outto find out effective weed control method.

The integration of herbicides with some cultural operations and use of pre-emergence, post-emergence herbicides in combination with mechanical methods can prove to be more successful. This way integrated weed management is gaining importance in management of weeds for preventing losses and higher input-use efficiency (Ishya et al., 2007).

A Field experiments were carried out from 2009-10 and 2010-11 to evaluate the efficiency of herbicides under different rice residue management practices in wheat. The herbicide treatments included application of sulfosulfuron alone and tank mix Sulfosulfuron 25 g/ha + metsulfuron 4 g/ha and isoproturon 1.0 kg/ha + metsulfuron 4 g/ha. Residue mulching reduced weed density, resulting in improvement of growth and yield attributing characters of wheat followed by residue incorporated and residue retained treatments.

An experiment entitled "Influence of pre and post-emergence herbicides on weed dynamics, growth and yield of soybean (Glycine max L.)" was conducted in Kharif season 2015 at research farm of BRAUSS, MHOW, (M.P.). The soil of the experimental field was medium black in texture, neutral in reaction (pH 7.60) with normal EC (0.45 dS/m) and medium organic carbon contents (0.72 %) and analysing low in available N (270 kg/ha), medium in available P (6.9 kg/ha) and high in available K (382 kg/ha) contents.

A field experiment on evaluation of herbicides for control of weeds in wheat (Triticum aestivum L.) was conducted at School of Agriculture, ITM University, Gwalior, Madhya Pradesh during the winter season of 2015-16. The experiment comprised of ten post emergence herbicides application along with weed free and weedy check treatments. Maximum weed control efficiency was observed in weed free treatment followed by Sulfosulfuron + Metsulfuron, Isoproturon and Sulfosulfuron treatments. Sulfosulfuron + Metsulfuron recorded lowest weed index.

A field experiment was conducted during kharif 2012 to evaluate the efficacy of different pre and post emergence herbicides in direct seeded rice. The chemical treatments included two pre-emergence herbicides namely pendimethalin 1000 g/ha and oxadiargyl 100 g/ha and four post-emergence herbicides viz. bispyribac-sodium 25 g/ha, fenoxaprop 67 g/ha, ethoxysulfuron 18.75 g/ha and chlorimuron-ethyl +metsulfuron-methyl RM 4 g/ha at 25 DAS. Weed free and weedy check were also included.

As pigeonpea is long duration crop, many flushes of weed germinate at the later stages which compete with the crop. It is therefore, essential to use the post emergence herbicides in conjuction with pre emergence herbicides for the effective control of weeds.

A field experiment was conducted during Rabi season of 2016-17 and 2017-18 at Agricultural Research Station, Banswara (Rajasthan) to evaluate the effective weed management strategy for enhancing productivity and profitability of chickpea. The experiment consisted of eleven treatments of PE (pendimethalin 30EC, pendimethalin 38.7CS, sulfentrazone 39.6 SC, imazethapyr 2%) and POE (fenoxaprop ethyl 9.3 EC) herbicides with weed free and weedy check was laid out in random block design with three replications.

To meet the food requirement of a huge population the food grain production need to be enhanced accordingly. However the goal of higher production must not come at the cost of heavy exploitation of natural resources. In order to attain higher yields, need of the hour is to develop and promote new technologies and reform agricultural research. Nanotechnology holds promise in improving the fertilizer use efficiency of fertilizers. The unique properties can be exploited beneficially for improving the nutrient use efficiency.

A field experiment was conducted to assess the effect of seeding methods and weed management practices on yield of aerobic rice and nutrient removal by the weeds under direct seeded aerobic rice. Among the seeding methods line sowing increased the grain yield than the broadcasting method. Among weed management all the weed management practices were found to be equally effective in reducing the uptake of nutrient by weeds and producing higher grain yield as compare to weedy check. However maximum yield was obtained with the application of Pretilachlor 0.
