在加拿大
尽管众玫瑰们在春风春雨的催动下长势喜人，含苞待放，但已发现不少叶子有虫眼。 最近开始发现有些已经孵化出来的浅绿色小虫，今早再经仔细研究，发现很多还完好无损的叶子背面竟然有很多尚未孵化的虫卵，有的一片叶子竟多达5个以上，可想而知过几天这片叶子的命运，现在看正面还是绿油油的新叶呢。 想请教诸位专家，应该用哪种杀虫剂啊，还有啥办法啊！！

Thebest control for flies is strict sanitation, exclusion and farmcleanliness. Stop the buggers ever getting a sniff. housesmust be airtight and all air vents must have filters. If you can affordto make your growing area a positive pressure zone, with filters on allair intakes, you'll be doing youtself a major favour in pest prevention.Watermanagement is crucial to controlling fungus gnat buildups: avoidoverwatering, and provide adequate indoor ventilation. Moving air isnot good news to fungus twats ... er gnats.ADDITIVES AS DETERRENTS:dried coffee grounds, tobacco water (from soaking cigarettebutts), chilli spray and garlic water have all also been toutedas possible deterrents. citronella candlesare reputed to deter many flying insects, including fungus gnats. also,crushed leaves of the herb 'tansy'can be sprinkled around the growing area: In Europe and in colonialAmerica in the 1840s, meat was packed in tansy or rubbed with it toprevent decay and to repel flies. The oil distilled from the plant,made a 'mosquito dope' useful to hunters and fisherman and others whohad to work where mosquitoes are troublesome.One major sourceof gnats is in their (microscopic) egg and larvae forms, in coco-coirand under-pasteurised manure-based substrates. Increase pasteurisationtimes and temperatures (being wary not to accidentally sterilise).Remove any standing water, or treat it with the long-term biologicalmosquito larvicide Bacillus Thuringiensis (variants H-14[Gnatrol] or Israelensis, BTI)weekly for two or three weeks as routine preventative control of fungusgnat larvae. This larvicide gradually settles in water where it iseaten by any mosquito or fungus gnat larvae growing there, which willbe killed continuously.BTI is used to make ‘skeeter dunks’ thatlook like little donuts (designed to float on water and killmosquitos), and will keep on working for 30 days or longer undertypical environmental conditions. While floating they slowly release atthe waters surface. Put some in water to be used for a day or two, toload it with the stuff.BTI:
You can also drench soil with neemextract. the fascinating Indian Neem Tree (Azadirachta indica) and itsunique extracts have an enormously broad range of applications. Theoil, extracted from neem tree kernels, has nourishing qualities and isused in India today in many toiletry ranges, including hair-careproducts, toothpaste and soap. Mahatma Gandhi believed firmly in thegoodness of neem and ate neem leaf chutney as part of his everydaydiet. The main substance azadirachtin, a tetranortriterpenoid,influences the hormonal system of insects, exerting thereby apesticidal effect. Feeding activity, reproduction and flying ability ofinsects are also affected. Azadirachtin has a very low toxicity tomammals, its biologically degradable and can be easily extracted fromthe seeds of the trees - it can be found as leaves, oil, powder orcoir. Note, though that Azadirachtin [Diazinon] has been withdrawn dueto fly resistance from many areas.
