Pythium in carrots: Cavity spot and forking in carrots
8 May 2017

Two Pythium species are mostly responsible for forking and cavity spot of carrots in Australia. In most cases, P. sulcatum cause the symptoms.

While some general rules apply, especially the need for managing soil moisture, pH, soil calcium and crop maturity; carrot producers should find their own optimum combination of additional management strategies that fit their production systems and growing conditions.

Read this useful fact sheet to find out more about what causes cavity spot and forking in carrots, as well factors affecting cavity spot development and management approaches.

Tobamoviruses - tobacco mosaic virus, tomato mosaic virus and pepper mild mottle virus: Integrated virus disease management

Tobamoviruses - tobacco mosaic virus, tomato mosaic virus and pepper mild mottle virus: Integrated virus disease management
15 Oct 2015

Tobamoviruses—tobacco mosaic virus (TMV), tomato mosaic virus (ToMV) and pepper mild mottle virus (PMMV) — are stable and highly infectious viruses that are very easily spread from plant to plant by contact. These viruses can survive for long periods in crop debris and on contaminated equipment. Although these viruses affect field crops, they are more often a problem in greenhouse crops where plants are generally grown at a higher density and handled more frequently.

Aphid-transmitted viruses in vegetable crops: Integrated virus disease management

Aphid-transmitted viruses in vegetable crops: Integrated virus disease management
15 Oct 2015

The majority of viruses infecting plants are spread by insects, and aphids are the most common group of virus vectors or carriers. All potyviruses (the largest group of plant viruses) are transmitted by aphids.

Aphids are sap-sucking insects and have piercing, sucking mouthparts. Their mouthparts include a needle-like stylet that allows the aphid to access and feed on the contents of plant cells. During feeding, aphids simultaneously ingest sap contents and inject saliva, which can contain viruses if the aphid has previously fed on an infected plant.

The structure of aphid mouthparts, their searching behaviour for host plants, the range of available host plants and high reproductive rates contribute to the efficiency of aphids to act as virus carriers.
