Liquid garden

The wide distribution of this insecticide in other cruciferous crops was investigated later, and the stability and occurrence of this compound were studied. Two cabbage varieties, cauliflower, brussels sprouts, broccoli, kale, mustard, and kohlrabi contained 2-phenylethyl isothiocyanate in various amounts as evidenced by gas-liquid chromatography and bioassay (houseflies and vinegar flies) (Table VII). Insecticidal activities were encountered only with root tissues. Compounds of insecticidal activity, not attributable to 2-phenylethyl isothiocyanate, were found in the edible parts of radish and leaves of turnip, rutabaga, and garden cress. 

The flexibility of some plastics can be improved by the addition of small molecules called plasticizers. For example, pure PVC turns brittle and cracks too easily to make useful flexible plastic products. With an added plasticizer, however, PVC can be used to make seat covers for automobiles, raincoats, garden hoses, and other flexible plastic objects. Plasticizers must be liquids that mix readily with the pol Tner. In addition, they must have low volatility so that they do not escape rapidly from the plastic. Dioctylphthalate is a liquid plasticizer that is formed by condensing two alcohol molecules with one molecule of phthalic acid, as illustrated in Figure 13-10.

Secondary sources of PCDD/PCDFs, their reservoirs, are those matrices where they are already present, either in the environment or as products. Product reservoirs include PCP-treated wood, PCB-containing transformers and sewage sludge, compost and liquid manure, which can be used as fertilizers in agriculture and gardens. Reservoirs in the environment are, for example, landfills and waste dumps, contaminated soils (mainly from former chemical production or handling sites), and contaminated sediments (especially in harbours and rivers with industries discharging directly to the waterways). 

Disulfoton enters the environment primarily during its use as an insecticide/acaricide in crops and vegetables, and in homes and gardens. Other important pathways for disulfoton s entry into the environment are the disposal of liquid disulfoton wastes into soil evaporation pits, ditches, ponds (Winterlin et al. 1989), and hazardous waste sites. Thus, soil is the environmental medium most likely to be contaminated with disulfoton. The processes that may transport disulfoton from soil to other environmental media include leaching to groundwater, runoff to surface water, and absorption by plants (Holden 1986 Mostaghimi et al. 1993 Nash 1974 Plumb 1991 Sanborn et al. 1977 ... 

Liquid seaweed extract (see alsop.l95) is a well-known plant tonic that can be used as a root drip, drench, or foliar spray, to help boost a plant s defenses against pests and diseases. There are a range of other plant-based tonics and stimulants available that are said to have similar effects. They may be worth trying while your garden is adjusting to an organic regimen. 

The pure chemical (100% diazinon) is a colorless and practically odorless oil. Preparations used in agriculture and by exterminators contain 85-90% diazinon and appear as a pale to dark-brown liquid. This form of diazinon is diluted with other chemicals before use. The diazinon available for home and garden use contains 1-5% diazinon in a liquid or as solid granules. These preparations have a slight chemical odor but cannot be identified by smell. Most of the diazinon used is in liquid form, but it is possible to be exposed to the chemical in a solid form. Diazinon does not bum easily and does not dissolve easily in water. It will dissolve in alcohol or other organic solvents such as petroleum products. Its basic physical and chemical properties are summarized in Chapter 3 for more information on its production and use, see Chapter 4. 

You can obtain an inorganic garden . For this purpose, pour 30-50 ml of a liquid glass solution into a beaker and drop crystals of cobalt, iron(II), aluminium, nickel, copper, and calcium salts into the solution. What is observed ...

If a stream of liquid is vibrated along its axis, the stream will break up into drops (pick a nice summer day and try it with a garden hose). The characteristics of this drop formation are governed by an equation that will be familiar to anyone who has studied light waves v = f/l, where v is the velocity of the stream, f is the frequency of the vibration applied, and k is the wave length or distance between the drops. One other fact that needs to be known before we can under-... 

Uses Chlordane is a viscous, amber-colored liquid. Technical-grade chlordane is a mixture of many structurally related compounds including trans-chlordane, cis-chlordane, chlordane, heptachlor, and /ran.v-nonachlor.14,15 Chlordane was used as a broad-spectrum pesticide in the United States from 1948 to 1988. Its uses included termite control in homes and pest control on agricultural crops (e.g., com, citrus, home lawns, gardens, turf, ornamental plants). 

Plant food may come in the form of a liquid or a powder. Gardeners dissolve the plant food in water, and then either spray or water the plant with the resulting solution. 

Gardener colour A measure of translucency as seen in the case of liquid epoxy resins. The Gardener scale ranges from 1 to 10. Transparent materials have a lower value on the Gardener scale.
