Suggested management strategies to minimize desiccation include spraying during the evening and using supplemental wetting prior to or following application. The number of sprays in the 'full protection' treatment varied between sites because applications were not started until disease symptoms appeared. Reduced feeding by caterpillars was termed a feeding restraint effect and the refusal to eat leaves sprayed with solution was termed an anti-feeding effect. The trial incorporated three varieties differing in their ease of retting, so that variety and time of spraying interactions could be investigated.

The method consists of spraying diluted honey (honey-water) on ground-level vegetation. Fenthion is sprayed at weekly intervals at a dosage of 0.78 ml/1 in polluted water, drains and trenches, which are the major breeding sites. Three fungicide sprays were applied in both these treatments. Significant seed-set was not observed in the control entries (male-sterile lines in absence of pollinators and insecticide sprays applied). The insecticide treatment history was obtained for each sprayed crop (table 1). Apart from spraying, there were no changes in the general management practices on any of the three farms during the entire study period. Often the intention is to study the interactions between the factors; in this instance, the best time for spraying might depend upon the fungicide used. There are three main methods of adding micronutrients to crops: soil fertilization, foliar sprays and seed treatment. Plots sprayed with insecticides were sampled at monthly intervals to confirm that the plants were free of insect damage. Trials were grown under a moderate-input management regime which included two insecticide sprays, no fertilizer application, and two weedings. Each dish was then sprayed, using a hand-held mister, with either water or the kaolin particle suspension. In six of the 10 replicates, only larvae on plants sprayed with chrysanthemum extract were parasitized (table 2). After turmeric water was sprayed around the tree, it was felled and brought back to the temple where the performance was to take place. Glycosphingolipids were visualized by spraying the plates with orcinol\\sulphuric acid. In addition, developments in biotechnology have produced genetically modified crops that are either able to survive spraying with herbicides or contain their own bioengineered pesticides. He would only employ labour for spraying as long as the labour costs are lower than his own opportunity costs for conducting that specific task. In its first year, 1956, over 3.3 million houses needed to be sprayed. An economic threshold model for spraying herbicides in cereals. Furthermore, the late instar larvae thriving inside the stem are inaccessible to insecticidal sprays. A baiting assay consisted of spraying diluted honey on vegetation along transects and recording bee arrival on the same day. Because of the frequent sprays of insecticides, the plots sampled were not chosen at random. When the fruit started to dry up through time, it was sprayed with water, then rolled and mixed to ensure all fruits were moistened. Art sprays a pesticide, and bugs fall dead at his feet. As in the first experiment, plants were sprayed twice in a ten-day interval. All trials were grown under a moderate-input management regime which included two insecticide sprays, no fertilizer application, and two weedings. The crop was hand-weeded when necessary and was given two or three insecticide sprays to control insect pests. Also, the benefits from saving time on spraying pesticides increase with an increase in the opportunity costs of the farm labour. As with chemicals, optimal application strategies are needed to maximize the effectiveness of nematode sprays. The rates will be a little higher with pourons than with dips or sprays, since pour-ons involve relatively large doses of active ingredient. The material is sprayed onto the crop as an aqueous suspension that dries to leave a white particle film on the plant surface. However, the electrospray ionization process produces multiply positively charged protein and peptide ions when spraying from acidic solutions. The plants in the control were sprayed with distilled water. Treated plots received 2 + 3 sprays at 10-d intervals, typically commencing at early -ower emergence. In the evisceration process, the carcass is sprayed with hot water. I sprayed a strong pesticide on the tree. Since then, black leaf streak has been controlled with contact and systemic fungicides, and with mineral oil sprays. Basically, production costs differ because organic systems require more mechanical treatments due to the fact that they are not using any fertilizers and sprays. Locusts that invaded the untreated area or hatched after spraying also had high mortality (fig. 1: open circles). Fourteen plants were sprayed twice at a ten-day interval with a 10 mg mlx1 methanol-water solution.

The remaining three trays were left as natural enemy-free controls, but were sprayed in the same way. All eight plots from which biocontrol agents were excluded were surrounded by a 1-m wide barrier zone sprayed with insecticides. The area received no insecticide sprays during the three previous years (local farmers' personal communication) and, therefore, it was assumed the population would be susceptible. In bark surface treatments, nematodes are sprayed over the entire trunk and may be concentrated around heavily infested areas. Many commercial varieties are susceptible to late blight and must be sprayed regularly with fungicides. No-till treatments were sprayed with glyphosate at 2 l ha71 to eradicate any standing vegetation during the week before planting.

In addition, almond growers in this study were characterized by their widespread use of foliar nutrient sprays, winter orchard sanitation for insect pest control, and burning of orchard prunings. Meanwhile, the occurrence and development of insect populations in the unsprayed plots were undoubtedly affected by the heavy sprays in surrounding plots because of the small sizes of unsprayed plots. The start of the 11-year period for the first significant running correlation in 1980 is very close to the introduction of spraying summer foliar fungicides for disease control (1979). Since certain insects, in particular, can cause substantial damage, the price bonuses provide added incentives for growers to use routine and broad-spectrum sprays as 'insurance policies'.
