Apple Fruit Thinning for Efficiency and Quality:
Evaluate the potential of mineral oil as an enhancer of thinning agents 

Under the Crop and Livestock Management Trials Program, a part of the Canadian Agricultural Partnership, and with contributions from the Nova Scotia Fruit Growers Association, Perennia was able to conduct a two-year trial investigating the efficacy of chemical fruit thinners on Honeycrisp apples. 

Sevin XLR (carbaryl) is a commonly used thinning agent, and in March 2018, maximum allowable application rates were lowered, which meant local growers needed to consider new thinning options. The trial was initiated to determine if adding mineral oil to common thinning agents would enhance thinning under lower application rates. Perennia collaborated with a local grower to establish the trial in an existing highdensity orchard, ensuring that management practices and growing conditions were consistent with that of the commercial crop. Perennia was responsible for trial design, data collection, treatment application, harvesting fruit, assessing fruit quality, data analysis and reporting. Results will be used to update local recommendations to outline more effective chemical thinning options for the industry. 

Further Innovations and Expansions for
Nova Scotia’s Burgeoning Sweet Potato Industry

Under the Nova Scotia Department of Agriculture Farm Innovation Program, Perennia worked with a local sweet potato grower and Horticulture Nova Scotia to carry out a number of agronomic field trials to explore and optimize the performance of this specialty crop in Nova Scotia. Perennia conducted small plot research to test the suitability of second and thirdgeneration sweet potato slips under development at the Vineland Research Station, Vineland, Ontario.

Both small plot and fieldscale trials were performed to experiment with row cover removal timing and several other agronomic parameters such as plant spacing, use of row cover and/or black plastic mulch. Perennia collaborated with the grower to establish the trials in commercial sweet potato fields, ensuring that management practices and growing conditions were consistent with that of a commercial crop. Perennia was responsible for the establishment of plots, planting varieties for variety testing, data collection on population, yield and marketability, data analysis and reporting. In addition, results were used to determine the potential for an earlier mid-September harvest to have product for the Canadian Thanksgiving market. The findings of this study can be used to determine local best management practices for this novel crop and help expand a new commodity within Nova Scotia’s horticulture industry.


Strawberry Aphid Monitoring and Virus Testing Program 

Perennia Food and Agriculture delivered the Strawberry Aphid Monitoring and Virus Testing Program on behalf of Horticulture Nova Scotia for berry growers in Nova Scotia. It was supported by the Nova Scotia Department of Agriculture as part of the provinces virus recovery strategy following the 2012-13 strawberry virus outbreak. 

The main program objectives are to monitor primary strawberry, and bramble insect virus vectors (strawberry aphid and large raspberry aphid) across the province employing various insect capture techniques; (2) ensure nursery stock produced in the province meets the recovery strategy requirements, and; (3) conduct a late summer virus survey of all newly planted strawberry and raspberry fields to evaluate the progress of virus management efforts in the province. Various iterations of this program were run from 2013-2021. 

Maritime Corn Hybrid Performance Trial 

Corn Hybrid Performance Trials were initiated in Nova Scotia by Gerry Smeltzer in the mid 1950s and were taken over by provincial extension in 1994. Due to its limited length of growing season, the Maritimes is a challenging environment to grow corn. These trials identify hybrids that have the right combination of early maturity and high yield. Of the 25 – 30 hybrids tested every year, about 15% have inferior yield or late maturity for the region. This allows producers to focus their production on the remaining high yielding hybrids. 

Perennia organizes the seed, plot layouts, data and compiles the final report for the five Maritime locations. The trial is a randomized complete block design with three reps, and each plot is a single row, 25 feet in length. Silage is harvested with a single row chopper, weighed, and samples are dried to determine moisture content. The grain plots are hand–harvested, shelled and subsamples are weighed and dried for moisture content determination. The final report is released each year in mid-November in time for producers to make decisions on their seed purchases.

Terroir Study of the Wine Growing Region of Nova Scotia 

Perennia led the ‘Terroir Study of the wine growing region of Nova Scotia: A complete study based on the interaction of soil, climate and plant growth. This study’s main goal was to evaluate the key wine growing parameters in Nova Scotia and provide the best management techniques and tools to the grape and wine growers of the Province for our local conditions, based on scientific results and technical information. 

In the Terroir Study, Perennia collaborated with established grape growers to evaluate vineyard performance and improve their management practices for considering the final wine. It took place during three consecutive seasons (2017-2019). Fourteen different vineyards were selected based on the interaction of soil characteristics, climatic conditions and agricultural practices. 

The most planted grape varieties of Nova Scotia were selected, four interspecific hybrids and four Vitis vinifera varieties. Perennia’s team evaluated plant physiological characteristics such as percentage of budburst, determination of main phenological stages, plant growth, uptake of nutrients through soil, petiole and blade analyses, water stress measurements and fruit ripeness. Agronomic characteristics were also measured. These included plant spacing, plant density, trellis system, vineyard management (weeds, pest and disease and canopy) and yield per vine. To complement these evaluations, winemaking was performed, which made it possible to understand the process and evaluate the improvements in the vineyard. 

All this information was analyzed, reported and presented to the grape growers to demonstrate which practices can help vineyard management in the specific conditions of Nova Scotia. These results are used in publications and presentations to provide accurate support to the local wine industry.
