Crop protection on major crops is now required to follow the principles of integrated pest management so the timing and accuracy of any application of a pesticide or biopesticide has to be more precise to minimize adverse effects on non-target species. The development of UAVs (unmanned aerial vehicles) provides a means of providing a more targeted application of the correct dose, especially by using formulations that are more persistent, thus minimizing loss of spray in areas subject to rain. Avoiding use of too high a dosage allows greater survival of natural enemies and reduces the selection pressure for pests becoming resistant to specific modes of action. The downward flow of air from a UAV should also provide better distribution and impaction of droplets within a crop canopy, reduce soil impaction caused by taking heavy loads of spray applied with 200 l ha–1 of water, and allow treatments when fields are too wet to access with ground equipment. In Asia, many smallholder farmers are using a drone in preference to using a knapsack sprayer. According to Matthews, it has been shown that ULV spraying can be effective, but it needs a narrow droplet spectrum with the droplets remaining stable and not shrinking to become too small. Formulation research can reduce the volatility of the spray, hence the success of oil-based sprays. However, instead of petroleum-based oils, there is a chance to develop vegetable oil carriers with micro-sized particle suspensions to deliver low toxicity pesticides in droplets that can be deposited within the crop and not drift beyond the crop boundary. Oil deposits will be less prone to loss after rain so less should be lost in neighbouring ditches and water courses, especially as rainfall patterns are forecast to change. More studies are needed to evaluate the swath for deposition, buffer zones, formulation, nozzle selection, to guide future specific legislation for UAV applications.

Abstract This experiment was conducted on fairways 10, 12, 13, 15 and 18 at the Jackson County Golf Course in Jackson County on the Gulf Coast of Mississippi. Soil type was a sandy clay loam. Mole crickets were midinstar nymphs Experimental design was a RCB with 4 replications. Each replication was 2,000 ft2. Treatments were made on 24 Oct. Granular formulations were applied with a Scotts ProTurf, hand-pushed spreader. Liquid and wettable powder formulations were applied with a Solo Knapsack sprayer using a fan nozzle at 25 psi, and a spray volume of 2 gal per 2,000 ft2. Rainfall from 24 Oct to 11 Nov was a total of 16.41 inches during this study. All plots received 0.33 inch water within 1 hour after applications. Mole cricket damage was rated using a 1 m2 frame divided into nine equal, square-shaped sections. The frame was placed on the ground at 10 locations/replicate. The presence of mounds and tunnels was determined visually and by touch. Damage ranged from zero (no damage in any of the nine sections) to nine (nine sections contained mounds and/or tunnels). Pretreatment counts were made on 24 Oct and post-treatmem counts were made on 31 Oct and 6, 13 and 20 Nov.

The present study was conducted in Gonda district of Uttar Prades. The purpose of the study was to know the adoption of selected drudgery reduction technologies related to agriculture by the farm women. The 100 farm women were randomly selected for technological empowerment through training from two purposively selected panchayat samities. Personal interview technique was used for collecting data. The findings of the study reveal that manual bund former, serrated sickle and maize sheller were the main technologies used by majority of the respondents as indicated by higher adoption index (60%). This may be due to reason that the technologies were easy to use and handle, cheap in cost, require less effort while operation as compared to traditional methods. Wheel hoe, manual seed drill and knapsack sprayer were the other technologies adopted by more than half of the respondents with adoption index 47.5- 50 per cent followed by manual rice transplanter and ground nut decorticator with adoption index 35-43 percent.

High infestations of Centaurea diluta (Lesser star-thistle) become a serious problem to cereal farmers in Ouazzane region of Morocco. The aim of this study is to investigate the effect of three post-emergent herbicides on C. diluta infestation in a soft wheat crop. The experimental design was Randomized Complete Block Design (RCBD) with three replications. Each block contained 4 elementary plots, 3 plots of which were treated with the three post emergent herbicides and the untreated plots serving as control. Trials were conducted in Ouazzane region of Morocco in January 2017. Treatments were carried out with a knapsack sprayer with the nozzle delivering a 3 bar jet. Calculation of reduction of biomass in C. diluta was carried out at weed research laboratory of INRA-CRRA Tangier in March 2017 using an oven at 75ºC for 48 hours. The weights were then taken using a precision balance. A quadrant of 1 m2 was used to calculate the reduction of density in C. diluta. Results showed that treatment with Aminopyralid + Florasulam at (9.9 + 4.95) g/ha and 2,4-D at 600 g/ha  gave the best control of  C. diluta infestations. In fact, Aminopyralid + Florasulam at (9.9+4.95) g/ha recorded 88±4.1%, 86±5.1% and 97±1.6% respectively on reduction of density, height and biomass in C. diluta. 2,4-D at 600 g/ha recorded 75±3.1%, 84±4.2% and 94±2.5% respectively on reduction of density, height and biomass in C. diluta. Tribenuron-methyl at 9.50 g/ha recorded the lowest efficacies recording 25±4.9%, 21±4.8% and 37±8.1% respectively on reduction of density, height and biomass in C. diluta. Thus, Aminopyralid + Florasulam at (9.9+4.95) g/ha and 2,4-D at 600 g/ha could be recommended to farmers in Ouazzane region when C. diluta infestation is dominant on wheat. A further assessment of Aminipyralid and Florasulam residues in soil and their phytotoxicities should be evaluated on other crops grown in rotations.

Kegiatan penelitian dilaksanakan di Kebun Aneka Persada, Riau mulai 6 Februari 2017 sampai  6 Juni 2017. Penelitian ini bertujuan meningkatkan kemampuan profesional, teknis, manajerial, dan analisis kegiatan di lapangan dengan melaksanakan kegiatan sesuai tahapan yang ada di lokasi penelitian. Pengamatan data primer yang dilakukan yaitu dominansi jenis gulma, metode pengendalian gulma, kondisi gulma dominan setelah semprot, metode pengendalian gulma yang digunakan, alat pelindung diri (APD), kondisi alat penyemprot<strong>, </strong>dan<strong> </strong>tenaga kerja<strong>. </strong>Hasil pengamatan pada 6 blok yang diamati menunjukkan bahwa vegetasi gulma yang dominan yaitu <em>A. intrusa</em>, <em>D. ciliaris</em>, <em>B. alata</em>, <em>M.bracteata</em>, dan <em>C. lapacea</em>. <em>Asystasia intrusa</em> mati setelah 3 MSA dengan herbisida berbahan aktif  Isopropilamina glifosat  480 g l<sup>-1</sup> + Metil metsulfuron 20 % dosis masing-masing 115 ml ha<sup>-1</sup> + 4,5 g ha<sup>-1</sup>. Hasil uji yang dilakukan bahwa parameter flowrate, kecepatan jalan, dan prestasi kerja terdapat perbedaan yang sangat nyata, yang berarti bahwa penggunaan MHS lebih efektif dan efisien daripada penggunaan knapsack sprayer karena luasan semprot yang dapat dicakup menjadi lebih luas
