There can also be soluble powders and wettable powders. Wettable ones are sold in measured amounts in sachets to be mixed in a sprayer and sprayed onto the plants.
Contact fungicides
These need to land on the fungal growth and kill the infection or you
need to coat the leaf
with the chemical. If
Wash out all utensils after use and wash your hands.
4. Mix only the required amount and use
it all. Mixed sprays will not keep till next
time; many cannot even be stored overnight without going off. Some can affect the material the sprayer is made from and others
can “set” in the sprayer and be very dif cult to remove especially if in the nozzle.
5. Only use a product that is recommended
for control of the particular problem
and for use on the particular crop. Details will be on the label.
6. Keep chemicals away from children, animals and ponds as some are harmful to sh.
7. Products recommended for use on edible crops have a “harvesting period”. This is the time which must elapse between spraying and harvesting. This will be on the label and must be adhered to.
8. Store all chemicals in a safe place and never store them in anything except the original container. A frost free shed or garage that can be locked to prevent children gaining access is the best place to store them. Do not store then for more than 18 months as the chemicals can degrade and lose their effectiveness is kept too long. They can also run out of approval date which means it is illegal to store them.
9. Do not eat drink or smoke while using chemicals and wash your hands after using them.
10. Pests and diseases can build up resistance to certain sprays, so alternate with different ones that are sold for the same purpose; but make sure it is a different active ingredient (chemical) in the product.
11. Do not spray in strong sunlight; the best time is in the evening when there are fewer bene cial insects about and the sun has gone down so the leaves are not scorched.
the leaves are covered
with the fungicide the
spores of the disease
are prevented from
germinating. This is
how copper sprays
work in preventing
infection from potato and tomato blight.
Systemic fungicides
These help to cure the disease and stop it from spreading as the chemical is absorbed into the plant and prevents the fungal disease getting hold.
It must be mentioned that some products may contain both an insecticide and a fungicide and will control both insects and fungal infections. However, it is illegal for people to mix chemicals like this unless the labels say that it is allowed.
Any chemicals used in the garden must
be used with care and treated with respect. The following are general rules to be followed when using any chemicals.
1 .Only use chemicals when necessary and consider cultural or biological control methods rst. Many pests and diseases can be minimised by sensible garden hygiene and crop rotation. Small infestations of caterpillars can be handpicked or, better still, look for the eggs and destroy them. Aphids can easily
be squashed or the tip of the plant removed along with the aphids.
2. The most important thing to do is to read the label and follow the instructions on the chemical container.
3. On no account use a sprayer that has been used for weedkiller as it only needs a trace of the chemical left in the sprayer and it could kill your crop; especially tomatoes.
Any chemicals used in the garden must be used with care and treated with respect.
Jack Morris FNVS
It is with much sadness and regret I must inform members Jack passed away in October of last year.
A much respected and long serving member, Jack was awarded the highest accolade of the Society, the Gold Medal, in 2002 following many years as Southern Branch Chairman. He was made the Branch’s rst President as a tribute to his many years of service when he stepped down from the chair in 2005.
My rst recollection of Jack was when
I was a ‘rookie’ member back in the
early nineties when he rst persuaded, then helped me form the Sussex District Association. From then I had the pleasure of serving as his Vice Chairman at a period of rapid development in the Southern Branch. During this time Jack was at
the forefront of establishing the Essex, Hampshire and Surrey DA’s and put many miles on the clock as a regular at events across the south as well as his frequent trips to Preston to serve on the then National Executive.
Jack’s credits with the NVS are numerous and include organisation of Chelsea displays, the National Championships at Tunbridge Wells and the successful transfer of the Southern Championships to the New Forest, of which he was particularly proud of.
As well as his long service to the NVS Jack was also very involved with the Surrey Horticultural Federation and the Surrey Guild of Judges and Lecturers. For the Guild, he was not only a very active judge himself, but served as its Secretary for many years.
In short Jack will be sadly missed by his many friends throughout the Society and our thoughts are with his wife Marjorie and the family.
