Effect of Compound Biochar Substrate on the Root Growth of Cucumber Plug Seedlings

Agronomy, 2020
Since plug seedling plays a key role in automatic transplanting, this work aimed to explore the effect biochar has on the root growth of plug seedlings. The physicochemical properties tests showed that the addition of biochar in the peats could increase ...

Uniformity of Impatiens Plug Seedling Growth in Controlled Environments [PDF]

Journal of the American Society for Horticultural Science, 1991
Uniformity of growth response of impatiens (Impatiems wallerana Hook. f.) plug seedlings was examined in four identical growth rooms. Differences among growth rooms for dry weight, height, and leaf area of 10- to 24-day-old seedlings were generally not significant. During six experiments over

Effects of bioinsecticide exposure route on aphids and their natural enemies in oilseed rape

Pest Management Science, EarlyView.
Fatty acids, silicone polymers and surfactants reduced aphid numbers but caused natural enemy mortality under direct exposure, while minimal residual activity suggests potential for targeted, compatible use in integrated pest management. Abstract BACKGROUND Myzus persicae Sulzer and Brevicoryne brassicae L.

Temporal dynamics of co‐inoculation of Leptosphaeria maculans and Leptosphaeria biglobosa determine interspecific competition and disease development on oilseed rape

Pest Management Science, EarlyView.
This study provides evidence that the timing of co‐inoculation of Leptosphaeria maculans and Leptosphaeria biglobosa determine the outcome of interspecific competition and disease development on their host oilseed rape. Abstract BACKGROUND Phoma stem canker is one of the most economically damaging diseases of oilseed rape, caused by co‐existing fungal ...

Determining frequencies of fungicide resistance in Leptosphaeria maculans that render demethylation inhibitor fungicides ineffective in the field

Pest Management Science, EarlyView.
As little as 1–10% of the population is needed to be resistant for demethylation inhibitor fungicides to be rendered ineffective. Following a single round of selection, the frequency increases by more than 15% with limited fitness penalty detected when no selection is present.

Resistance of Botrytis cinerea to anilinopyrimidine fungicides: A novel ARMS‐PCR method for the detection of Bcpos5 mutations and characterization of resistance using CRISPR/Cas9 editing

Pest Management Science, EarlyView.
A TETRA‐primer amplification refractory mutation system polymerase chain reaction (T‐ARMS‐PCR) method was developed for simultaneous detection of the L412F/V and G408V mutations. L412F/V mutants were created using the CRISPR/Cas tool and no fitness cost was observed.

Growing Vigorous Potato Seedlings in Plug Trays

Potato Research
Abstract Raising vigorous and healthy potato seedlings from hybrid true potato seeds (TPS) under nursery conditions is critical for ease of field transplanting and seedling crop establishment as well as for a productive seed or ware crop. The use of plugs in seedling production systems is an important technique utilised to ease transplanting ...
