Is it worth being totally organic on an allotment?. Some would jump in and say yes straight away but is it totally practicable. Although I do not like to use chemicals as an answer to any problem that arises on the allotment I do use them in a limited amount. I personally view is that used in a limited and responsible way that they have their place on the allotment. There are several reasons for this thinking. Firstly I believe that unless every plot is occupied and that all plot holders are totally organic there is always the problem with over spray and drifting of chemicals. Also there is
the problem of the pest population wandering from plot to plot in search of the best source of food available. I have noticed that when my nieghbour clears their plot of brassicas and runner beans that the aphid population on mine goes through the roof so the amount of organic control needed in such things as companion planting and defensive herb planting needed to cope with this invasion would drastically reduce the area left to grow productive crops. Although the appllication of soft soap and garlic mixes might reduce the level of some pests it is times like these when something stronger is needed and help from the chemical market is the only answer. A insectiside based on Pyrethrum would be the one of my choice here as it comes from a natural source.
As for the slug and snail problem I only use slug pellets as a last an under the nets of the brassica cage resort much prefer liquid treatment that does not harm birds A sprinkling of grit each side of a row of lettuce and the like work well as do beer traps and good housekeeping (removing dead and decaying foliage)
On the weed front although I swear by the regular use of the hoe for keeping weeds from establishing the smallest foothold on the plot there are instance when the most practicable answer is a weed killer. I would always advocate the use of one that leaves no residue in the soil. With a vacant plot bordering yours it quite possible that deep rooted and invasive plants and weeds will encroach into your plot and although hoeing weakens these it will not eradicate the problem In this is when I reach for a hand spray of weed killer and a 2 Lt. pop bottle with the bottom cut off. I place the pop bottle over the invading weed place the nozzle through the top and apply a quick spay . This method avoids drift from coming in contact with any other plant. I have found this works well with all types of plants including Mint raspberry bindweed and comfrey although some do need repeat applications
