Controlled potato

Fig. 1. IC-RT-PCR of potato latent virus. Agarose gel analysis of IC-RT-PCR assays from infected potato plants, immunocaptured using a PVS° polyclonal antibody, which also had affinity to potato latent virus (10). Lane M 100-bp molecular weight standard (SuperLadder-Low ABgene) lane 1, negative control (water) lane 2, positive control (potato virus S) and lane 3, potato latent virus.

Carbaryl or sevin [63-25-2], the first carbamate in use as a pesticide was introduced in 1956. This compound is a contact insecticide used as a spraying powder against mites in winegrowing and in a variety of crops. Also, in combination with lindane [58-89-9] it is used to control potato bugs. Carbaryl is produced from 1-naphthol by reaction with methylisocyanate or by treating 1- naphthol with phosgene followed by methylamine. It is the most heavily used pesticide among all carbamates. 

CioHgC NOiS. A protective non-systemic fungicide used principally for the control of potato blight. M.p. 160-161 C. It is relatively non-toxic to most animal life although it is harmful to hsh. 

Naphthalene acetic acid is used to thin apple and pear blossoms and to control apple and pear preharvest drop (10). It also is used to induce flowering in pineapple, but conversely inhibits sprouting in potatoes, sweet potatoes, and turnips (Brassica rapd) (23). It also is used to promote rooting in... 

Starches, used first in the late 1930s for filtration control (71), are stiU in use in the 1990s. Com starch is most commonly used in the United States. Potato starch is also used in the United States but primarily in Europe and elsewhere. Both com and potato starches are pregelatinized before dispersion in water (72). The API specifications for drilling fluid starch are listed in Table 8 (73). 

Diphenylamine inhibits the development of scald disease during prolonged cold storage of apples and pears (42—45). It prolongs the fresh appearance of cut snapdragons (46), controls weather fleck in tobacco, inhibits algae formation, and shows growth inhibitory activity in potatoes (47). 

One of the commercial methods for production of lysine consists of a two-stage process using two species of bacteria. The carbon sources for production of amino acids are corn, potato starch, molasses, and whey. If starch is used, it must be hydrolysed to glucose to achieve higher yield. Escherichia coli is grown in a medium consisting of glycerol, corn-steep liquor and di-ammonium phosphate under aerobic conditions, with temperature and pH controlled. 

Electrolyte leakage. Tissue discs, prepared from potato tubers as described above, were incubated for 16 h at 25°C between wet filter papers. After incubation, the discs were shaken in 20 ml H2O for another 60 min. One ml of this extract was diluted 30-fold with water, and subjected to conductivity measurements using a HI 8788 apparatus (Hanna Instruments). An increase in conductivity indicates a leakage of electrolytes through lesions in the cell wall caused by enzyme action. Control samples were not incubated, they were shaken in water only.
