Field studies were carried out at Adaptive Research Farm, Sheikhupura Punjab, Pakistan having rice- wheat cropping system to evaluate the efficacy of three different fungicides against seed or soil borne wheat diseases (Root rot, Loose smut & Black Point disease) during two successive seasons 2015-16 & 2016-17.The fungicides were Thiophenate methyl, compound fungicides i.e. Tubeconzol+ imidachloprid and Difenoconazol + cypnoconazol used as seed treatment at the rate of 2.5 g , 4 ml & 1 ml per kg of seed respectively. Incidence of root rot, loose smut & black point disease was recorded by selecting 15 plants, 100 plants & 100 seeds randomly of each treatment from each plot respectively in comparison with untreated control. All the fungicides significantly increased the seedling emergence per square meter about 15 percent as compared to untreated plot. Tubeconzol+ imidachloprid and Difenoconasol +cypnoconazol were the most effective seed dressing fungicide and reduced the number of rotted roots , loose smut infected spikes and black point infested seeds. Maximum number of productive tillers per square meter, healthy grains per spike and yield kg per hectare were recorded with compound fungicide Tubeconzol+ Imidachloprid followed by Difenoconazol + Cypnoconazol treated plots as compared to untreated plot.

Vitavax (2,3-dihydro-5-carboxanilido-6-methyl-1,4-oxathiin) applied as a seed treatment at a rate of 113 g per 45.4 kg of barley seed gave complete control of loose smut under field conditions. The seed treatment increased yield significantly in Parkland where smut in untreated plots was 49%. In York, with 16% smut in plants grown from untreated seed, yield increases were not significant. A higher dosage (227 g) also controlled smut but appeared to cause some toxicity. Seed treatment had no apparent effect on the malting quality of the seed subsequently harvested.Plantvax (2,3-dihydro-5-carboxanilido-6-methyl-1,4-oxathiin-4,4 dioxide) applied as a soil treatment at the rates of 5.6 kg/ha and 11.2 kg/ha also resulted in effective loose smut control in York barley but did not result in increased yield. There were indications that yield was depressed at the higher rate in York and at both rates in the variety Herta.There were also indications that treatments with either chemical had a slight effect on height, date of maturity, weight per hectoliter and 1,000-kernel weight. Seed treatment at planting time did not prevent infection of barley florets by loose smut spores 55 to 60 days after planting.

The Imidacloprid insecticide, Gaucho 70 WS at 1.5, 2.5, 3.5, 4.5 and 5.5 g/kg seed was used as seed treatment and monocrotophos 40 WSC at 1120 ml/ha was applied as foliar spray on CB9 cotton cultivar to suppress aphid, whitefly and thrips, and impact on their natural enemies during 2008-2011 at the Regional Cotton Research Station, Dinajpur, Bangladesh. The activity of natural enemies, such as ladybird beetle, lacewing, syrphid, and spider population on the sucking pests attacking cotton cultivar CB9 and yield of cotton were recorded. Imidacloprid significantly reduced aphid, whitefly, and thrips population on cotton crops compared to untreated control or foliar spray of monocrotophos 40 WSC at 1120 ml/ha. Ladybird beetles, lacewings, syrphids, and spiders were abundant in the field but their population decreased in the treated plots compared to untreated control. The CB9 cotton cultivar produced significantly higher yield (1.73 t/ha) with a benefit cost ratio 12.47 when seeds were treated with Imidacloprid at 5.5 g/kg fuzzy seed. This study indicated that Imidacloprid (Gaucho 70 WS) used as a seed treatment may be suggested to the cotton growers for controlling sucking pests. Bangladesh J. Agril.

Sowing Seed

In conditions of climate change, when temperature and precipitation fluctuations occur more and more frequently during the growing season, it is necessary to obtain high quality seedlings with "immunity" to various stress factors, including high weediness, the damage from which is associated with a decrease in yield (by 25 -35%) and with a deterioration in the quality of agricultural products. Due to the imbalance in production technology, seedlings are often weakened, overgrown, with a low yield per unit area and survival rate in the field. One of the solutions to this problem is the use of PP for pre-sowing seed treatment to increase the competitiveness of seedlings in the field.
