Makluk Perosak Whitefly.....bahaya ni...
Whitefly
Introduction



Introduction
Whitefly look just like they sound - small white flies that can be found on the leaves of plants - both on the upper and lower surfaces, but mainly on the latter.
These are the adults, which feed on growing shoots and lay eggs that hatch into tiny white scales that remain attached to the underside of leaves. Like aphids (greenfly, blackfly), whitefly scales are sap-sucking insect pests. This sap sucking weakens the plant and may introduce plant viruses that further weaken the plant, and may even kill it.
Whitefly scales (larvae) on the back of a leaf(much magnified).
Whitefly adults(much magnified).
Unfortunately, whitefly don't go round in ones or two - they go round in hordes of hundreds and a severe attack can severely weaken a plant. You will often see a 'cloud' of whitefly flying away from a plant whose leaves have been disturbed.
But this has another drawback, too. The large amounts of sugar-rich exudate they excrete plays host to a fungus called sooty mould. When the exudate lands on leaves below where the whitefly are feeding, these leaves then become covered in sooty mould. Although this does no direct damage, it does stop the leaves from receiving sunlight, so they are unable to manufacture food for the plant (photosynthesis). Some gardeners believe they have a disease problem when, in fact, they have a pest problem!
Whitefly tend to be more of a problem in greenhouses and indoors, but one species is very troublesome on brassicas, ans another on tomatoes and related crops.
Control
Sadly, whitefly can be difficult to control - some people say impossible - because they have a very fast lifecycle; they can develop from egg to adult in as little as three weeks in the summer. This means that if you are using chemical pesticides to kill them (generally it is only the adult that is affected) you have to spray very regularly to control a severe outbreak. And then you have to be very vigilant to catch other outbreaks early. If you've only a few plants it is simpler to check over them regularly and squash adults and scales (you can just about see them) as soon as they appear.
Prevention is better than cure and covering plants with a layer of horticultural fleece will stop the pest getting at them - although it might not look very pretty!. But brassicas can easily be protected as long as uninfected plants only are covered; the edges are buried in the ground, and the fleece is kept on until harvest.Covering greenhouse vents with fleece and making a door screen from the same material will help reduce attacks under cover.
There are a number of chemical pesticides that you can use on whitefly. Those containing bifenthrin and thiacloprid provide the best control.
Bayer Provado Ultimate Bug Killer is systemic and is taken up by the plant where it will help control whitefly - and other sap-sucking insects. There are only certain edible crops that the ready-to-use formulation can be used on; check the label before using.
In the greenhouse you can catch them by hanging yellow sticky traps just above the leaves of plants - they are attracted to the colour yellow, which is why I've never been able to work out why growing-bags are that colour! Some people even vacuum their plants regularly to remove the little flying pests!
Biological control
Whitefly are best controlled in the greenhouse by biological control - using another insect that kills them and so do the work for you.
Encarsia is a small parasitic wasp which lays its eggs in the scales where the larvae develop and so kill the scale The larvae hatch into adults which find more scales to parasitise. However, once it has done its job there is no food source for the larvae and so the lifecycle stops. If a further outbreak occurs then you have to re-introduce the encarsia. Luckily, encarsia rarely kills all its hosts so there are usually some to carry on the lifecycle. The second is delphastus, which is a member of the ladybird family.
This predator eats all stages of the whitefly.-->
Encarsia is available from various mail order suppliers, including Defenders, who also has a very useful Pest Problem Solver booklet.
In order to keep your whitefly killers safely within the greenhouse where they will sort out your whitefly problem, it's a good idea to again use fleece over the vents and doors. And, you can't use insecticides (although soft soap can be used before the controls are introduced) while the controls are busy at work - so you'll have to trust them.

Teknologi fertigasi lumayan
Dr. Mahamud Sahid antara pakar dalam teknologi fertigasi tekun membimbing bakal usahawan menggunakan sistem tersebut.
Sektor pertanian di negara ini telah melalui pelbagai perubahan bermula dengan kaedah konvensional hinggalah kepada pengeluaran yang memerlukan teknologi tinggi bagi meningkatkan produktiviti dan kualiti tanaman yang dihasilkan.
Salah satu daripadanya yang mendapat tempat di kalangan petani moden masa kini adalah sistem fertigasi pengeluaran tanah rendah.
Pegawai Penyelidik Kanan, Pusat Promosi dan Pembangunan Teknologi, Institut Penyelidikan dan Kemajuan Pertanian Malaysia (MARDI), Dr. Mahamud Shahid berkata, sistem fertigasi merupakan pengeluaran tanaman tanpa tanah yang menggabungkan pengairan dan baja dalam satu sistem.
"Biasanya diletakkan di bawah struktur pelindung tanaman bagi menjamin pengeluaran hasil tinggi dan berkualiti serta menjadi alternatif terhadap sistem konvensional," katanya semasa ditemui di pejabatnya di Serdang, Selangor, baru-baru ini.
Umumnya hanya beberapa jenis sayur-sayuran dan buah yang mempunyai nilai pasaran tinggi seperti cili merah, tomato, timun, zukini, terung, melon dan strawberi.
Tujuan asal fertigasi adalah untuk mengelakkan tanaman daripada jangkitan penyakit akar seperti Pythium, Fusarium, Rhizoctonia dan penyakit layu bakteria yang kebanyakannya bawaan tanah.
Walaupun ramai yang mengatakan kaedah fertigasi melibatkan kos yang tinggi tetapi sebenarnya kos permulaan dapat diatasi selepas satu musim selain mengurangkan penggunaan air dan baja.
Sementara itu penggunaan tenaga kerja yang minimum dengan penggunaan alat pengatur masa automatik mengurangkan kos.
Biasanya kos pada musim pengeluaran pertama adalah lebih tinggi berbanding dengan musim ke dua dan seterusnya.
Pada musim kedua dan seterusnya, kos menjadi rendah kerana medium masih boleh digunakan sehingga tiga atau empat pusingan jika diuruskan dengan baik.
Biasanya selepas satu pusingan, medium akan dirawat racun kulat sebelum digunakan semula pada pusingan akan datang.
Sehingga kini sejak fertigasi dimulakan terdapat ramai petani yang menggunakan teknik tersebut dalam tanaman mereka.
Dr. Mahamud berkata, fertigasi jika dilakukan dengan teliti dapat menjana pendapatan lumayan kepada petani.
"Sejak akhir-akhirnya kajian yang dijalankan mendapati halia sesuai ditanam secara fertigasi kerana boleh ditanam di tempat yang sama tanpa risiko dijangkiti dengan penyakit akar.
"Persekitaran dan suhu juga boleh dikawal dengan kaedah fertigasi," katanya yang menggunakan baja khusus bagi rizom.
Halia yang ditanam secara fertigasi hanya mengambil masa empat setengah bulan bagi menghasilkan sehingga 14 kilogram rizom dalam satu polibeg.

Pertanian adalah perniagaan....
Assalammualaikum.
Kali nie saja nak bagi tau kengkawan yg belum tau, saya telah meresignkan diri dari kilang Jabil Circuit pada January 2009 dan kini telah menjadi pak tani sepenuh masa. Semoga Allah SWT melimpahkan rahmatNya dan membuka seluas2nya pinta rezeki, amin.
Pertanian adalah perniagaan, jadi segala2nya hendaklah mengikut kaedah perniagaan. Dalam perniagaan segala belanja untuk operasi adalah dikira sebagai kos, jadi pengusaha hendaklah memastikan kos atau belanja yg dikeluarkan adalah minimum seminimumnya bagi menjana keuntungan yg lebih. Sebenarnya saya pun tak ada pengalaman dalam bab perniagaan ni. Tapi bila difikirkan kaedah yg kilang2 gunakan, memang jelas derang mengawal kos dengan berbagai kaedah.
Memandangkan saya nie zero dalam perniagaan jadi awai2 lagi saya dah prepare untuk belajar bab2 perniagaan dengan mengikuti kursus2 yg berkaitan perniagaan anjuran MARA n juga KBS.
Apa juga yg kita nak lakukan kita perlu belajar n jangan segan atau malu untuk belajar sebab tanpa ilmu kita tak kan kemana. Kaum cina memang terkenal dengan perniagaan jadi tak salah rasanya kalau kita cuba mendekati mereka n korek sikit2 ilmu bab berniaga.
Apa2 pun semoga Allah SWT mempermudahkan urusan kita n memberikan perlindunganNya. Kepada kengkawan yg mungkin dah lama berniaga n bertani saya harap dapatlah hendaknya memberi tunjuk ajar kepada saya yg masih baru dalam bidang nie...sekian wassalam.
