Selective Pesticides

Herbicides and plant growth regulators are often used in sugarcane management. However, the use of non-selective pesticides can cause adverse effects on the efficiency of beneficial insects in integrated pest management. Within this context, this study aimed to evaluate the effect of such products on the immature stages of the parasitoid Trichogramma galloi. Eggs of Diatraea saccharalis containing the parasitoid at the egg-larva stage and at the prepupal and pupal stages were immersed in test solutions of the following pesticides (maximum recommended doses for sugarcane): herbicides clomazone and diuron + hexazinone, and plant growth regulators trinexapac-ethyl and sulfometuron-methyl. The biological properties evaluated were emergence (F1 and F2) and number of eggs parasitized by T. galloi (F1). The products were classified according to percentage of reduction in emergence and parasitism: harmless (<30%), slightly harmful (30-79%), moderately harmful (80-99%) and harmful (>99%). The pesticides evaluated were considered to be harmless or slightly harmful to immature T. galloi and, thus, their use should be preferred for preserving this parasitoid species in sugarcane management programs.

Abstract Multiple applications of three rates each of B-Nine/Cycocel, Sumagic, Cutless, and Atrimmec were applied to common periwinkle grown in small containers in a greenhouse to control runner growth. All plant growth regulators (PGRs) suppressed runner elongation throughout the 30-week study. However, Atrimmec at 1500 to 4500 ppm severely injured plants for up to 20 weeks, and Cutless at 30 to 90 ppm reduced the number of runners for at least 24 weeks. There were no adverse effects associated with the application of B-Nine/Cycocel or Sumagic at the rates tested, 2500/1500 to 7500/1500 ppm and 15 to 45 ppm, respectively.

The Rose

Rose flowers are in great demand among the population. The use of growth regulators on the culture of roses allows you to improve the biological properties of varieties, their potential, as well as increase the yield and decorative colors. The purpose of the research was to determine the effectiveness of the action of plant growth regulators Biolan, Regoplant, Bionur, Bouton, Humisol-H and Zircon on growth, development, decorative qualities, yield dynamics and rose productivity under conditions of modern winter Venlo greenhouses. The study was conducted on plants of a variety of hybrid tea type Avalange of the Netherlands breeding company Lex +. Experimental work was carried out at the farm “Askania-Flora" during 2015-2016. Threefold spraying of plants with growth regulator solutions was applied: 7 days after planting, during budding and at the beginning of flowering. The control plants were not treated with growth regulating agents. As a result of research, it has been established that growth regulators Bud and Bionur accelerated the formation of flowering shoots and the time for slamming on plants, shortened the period of bud appearance and flower development. Established a different effect of preparats on the dynamics of the arrival of the crop by month. The influence of growth regulators Biolan, Bionur and Bud on the increase in total yield, plant productivity and decorative qualities of the rose flower has been determined. The results obtained should be taken into account when laying rose stands in winter greenhouses to regulate growth processes, plant development and increase crop yields.

Minor Crops

The pest management industry does not have adequate financial incentives to develop the required data to register pest management tools with government authorities on fruit, vegetables, herbs, spices, nursery crops, landscape plants, flowers, turfgrass, and other specialty crops. Growers of these crops, collectively called minor crops, need pest control tools to be able to sustain production. The Interregional Research Project Number Four (IR-4) was established in 1963 by the U.S. Department of Agriculture to assist growers of minor crops by providing a mechanism to allow growers of these crops to have access to safe and effective pest management tools. Working with research, industrial and extension personnel at the state land-grant institutions and researchers at USDA, Agricultural Research Service, IR-4 develops the appropriate data to support registration of insecticides, fungicides, herbicides and plant growth regulators. Many of the uses of plant growth regulators in current use were developed with oversight provided by IR-4. There are many promising new plant growth regulators and/or uses in the commercial development pipeline and it is anticipated that assistance from IR-4 will be needed to support registration of these new materials on minor crops.
