Fig Pest

first_imgBackyard fig gardeners may be seeing toothpick-like spines protruding from their beloved fig trees. This is a sign that ambrosia beetles are boring into the tree’s stems.Ambrosia beetles commonly attack weak or dying plants, such as fig trees that were damaged by the subzero temperatures last January. Healthy trees can withstand attackIf the plant is vigorous enough, the beetles may be drowned or forced out by heavy sap flow. If the host is weak or not producing large amounts of sap, the attack will be successful.Ambrosia beetle infestations can usually be identified by dust protruding from holes bored by females excavating their galleries. The strings or spines of the “boring dust” may be up to 2 to 3 inches long, but are fragile and easily broken off by wind or rain. The beetles are active during warm periods of the year, but most adult activity is observed in early March. They mate, lay eggs and rear young within the tunnels excavated by the females. There can be several generations in a year. They breed in stems that are 2 to 30 cm in diameter, although smaller branches are most commonly attacked first. They like other trees, tooAll life stages can be found inside the galleries. When mature, the females leave infested plants and fly to new host plants. And they don’t just attack fig trees. Ambrosia beetles are known to attack pecan, peach, plum, cherry, persimmon, oak, elm, sweet gum, magnolia, buckeye, crape myrtle and maples, too. Adults and larvae bore into twigs, branches or small trunks of woody host plants, excavate a system of tunnels in the wood or pith, and introduce a symbiotic ambrosial fungus. The beetles are highly specialized and feed on fungi they cultivate on the walls of the galleries. Both the adults and larvae feed on the fungus. The introduced fungus and tunnel excavating damage and clog the plant’s xylem (tissues that transport water), ultimately killing all or part of the plant. Prune or spray before adults emergeControlling ambrosia beetles is difficult. Heavily infested plants or plant stems should be pruned out and burned immediately. Insecticide sprays are of limited value after a plant is infested, especially if the host plant is already very weak or dying. Insecticides must be applied before the adults emerge and move on to attack other plants. Insecticide applied to the trunks of surrounding plants may help reduce the spread of infestations to other susceptible hosts. Using proper horticultural practices to keep plants healthy will help prevent future attacks. This includes properly fertilizing, maintaining proper soil pH and keeping the soil moist.

Barry says virtual training sessions a good way to assess fitness

first_img… Jaguars physio lauds attendance, feedback from cricketersBy Clifton RossGUYANA Jaguars physiotherapist Neil Barry Jr said his virtual training sessions with the national team have been coming along nicely, despite the physical limitations due to lockdown.Barry, who heads up the Jags’ strength and conditioning sessions, told Chronicle Sport yesterday that he has been enjoying the time spent virtually with his players, as it has been helping to somewhat keep track of what players have been doing during their downtime.“We’ve been online since the premature end to the 1st class season and restrictions started to be implemented. Virtual sessions have been good to help maintain some aspects of the player’s fitness, taking into consideration access to different training too,” he stated.Speaking on the pros and cons for this virtual method of the training, Barry said that the online forum keeps players in a good mental place while maintaining the social distancing guidelines.“One of the cons is that everyone will not have the same training space or equipment available, so it allows us to innovate while still trying to maintain professional standards. Another good reason is that it allows the players to still foster a bit of team spirit even though we’re all practising physical distancing”. Barry outlined.The Jaguars stars have been enjoying their time off while having to use their living spaces for makeshift training. The physio also gave insight regarding the logistics behind the sessions.“So far the sessions have been well attended and we’ve been getting good feedback. We’ve been working on injury prevention, muscle strength and cardiovascular conditioning among other aspects of training.The feedback from the players has been great and some have talked about feeling leaner and stronger,” said the team physio.With the uncertainty looming over the entire world with regard to the pandemic and its aftermath, Barry said he has been working on ways to ensure – should virtual sessions become essential – he’s fully prepared for the long haul.“Everyone is assessing the situation and taking it in stride. As the world develops more mitigating factors, chances are some restrictions will be lifted so online sessions are likely to reduce over time. Ultimately the players need the opportunity to practise their skills, so they need to be able to return to training facilities as soon as it is safe.”Barry said looking ahead to the future, to a post-COVID-19 world, working and rehabbing players will have to undertake a new chapter.“Even the physiotherapy world has resorted to something called tele-rehab so for now all interactions are done remotely. Rehabilitation is a very hands-on field so as soon as it is safe we would want to return to that type of practice.” he concluded.Guyana Jaguars team physio Neil Barry Jr has been conducting virtual sessions with team members.last_img read more
