Abstract
Abstract The invention provides seed dressed as defined in the specification with from 0.1 to 28g of 2,2-dimethyl-1,3-benzodioxol-4-yl N-methyl-carbamate per kg of seed.
Description
Ihis invention concerns dressed seed.
In one aspect, this invention provides seed dressed with i from O.lg to 28g, preferably not more than 18g, and more preferably from 0.25g to lOg, of 2,2-dimethyl-1,3-benzodioxol-4-yl N-methyl-carbamate per kg of seed.
By the term 'dressed' as used herein is meant that the seed is either in intimate admixture with the 2,2-dimethyl-1,3-benzo-dioxol-4-yl N-methylcarbamate or is coated therewith. Most desirably, the seed is dressed with the carbamate either by dusting with a dry composition or by a conventional spray-coating technique in which the carbamate is dissolved or dispersed in a volatile solvent which is sprayed over the seed and allowed to evaporate, '.'7 or by a conventional pelletising process in which the carbamate -- is mixed with a solid carrier, e.g. a clay or woodmeal, and the seed is coated with the mixture. Naturally, the technique chosen will to some extent depend upon the seed to be dressed. Seeds w~ich may be dressed in accordance with the invention include, merely as examples, vegetables, notably brassicas, onions and beans (for exa~ple soya bean~), cereals, notably wheat, barley, oats and maize, and root crops, especially sugar beet. The dressing treatment applied to each will normally depend upon conventional treatment for such seed. Thus, sugar beet seed, which is often pelleted, will normally be dressed in accordance with the invention by pelletisation. Cereals, however, which are not normally pelleted, will preferably be dressed in accordance with '':

~ The dressed seed of the present invention shows surprisingly ! high seedling emergence and establishment in the presence of ~ insect pests, and it appears moreover that the carbamate may i surprisingly be absorbed systemically by the seedling to provide ¦ post-emergent resistance to insect attack.
In another aspect, this invention provides a process wherein seed is dressed with from 0.1 to 28g of 2,2-dimethyl-1,3-benzo-dioxol-4-yl N-methylcarbamate per kg of seed.
Insects against which the present dressed seeds are effective include coleoptera and diptera, for example wireworms (Agriotes SPP) pygmy beetle (Atomaria), collenbola and millipedes, symphilids and flea 1 beetles (Chaetocnema ~pp).
I In another aspect~ erefore this invention provides a method of insect control in which seed dressed in accordance with the present invention is planted so as to give a concentration of carbamate per hectare of from 0.2g to 400g in a loous either infested with or liable to infestation by said insects. The concentration of carbamate per hectare naturally depends largely ; on the rate of plantIng of the seeds, and this varies with the chosen crop. Thus, for example, a preferred concentration of : carbamate when sugar beet is the chosen seed is from l-lSg per hectare, whereas if a cereal crop such as wheat is employed, the preferred rate may well be 200g/hectare or more.
The seed dressed according to the present invention may contain, in addition to the carbamate, other active insecticides ., .

f or fungicides. Particularly useful are mixtures with fungicides, ¦ for example thiram, benquinox, captan or S-ethyl N-(3-dimethylamino-I propyl) thiocarbamate or salts thereof, e.g. the hydrochloride.
! A further insecticide may also be applied to the soil, usually in a granular formulation, at the time of sowing the seed dressed in accordance with the present inYention. Examples of such insecticides are aldicarb, carbofuran, phorate, disulfoton, dimethoate, chlormephos, fonofos, diazinon, hexachlorocyclohexane, S-t-buty]-thiomethyl 0,0-diethyl phosphorodithioate and 3,3-dimethyl-1-methylthio-2-butanone 0-(methylcarbamoyl)oxime. 2,2-Dimethyl-1,3-benzodioxol-; 4-yl N-methylcarbamate may also be soil-applied.
