Impact of efficient protective chemicals on seeds yield of white lupin

Abstract

The white lupin is a source for qualitative plant protein to provide balanced nutrition for animals and poultry. Seed and green mass yield of modern lupin varieties can be 3–5 t/ha and 70–120 t/ha respectively. In spite of valuable qualities the production crop use is insufficient. One of the reasons is infection by diseases and pests. Anthracnose is the main dangerous and harmfulness disease. As a result lupin is in dire need for high effective protective chemicals. High effectiveness (97–96%) of seed dressers Vitaros – 2.0 l/t, Maxim XL – 2.0 l/t, Divident Star – 0.5 l/t, Selest Top – 0.7 l/t, Inshurperform – 0.7 l/t was revealed against seeds’ infection with anthracnose and other diseases under field conditions. The fungicides Amistar Extra – 0.5 l/ha, Spirit – 0.7 l/ha, Rakurs – 0.4 l/ha, Kolosal Pro – 0.4 l/ha, Bamper Super – 1.5 l/ha and Zantara – 1.5 l/ha are of high effectiveness (88–93%) for protection of lupin crops. The insecticides Tabu – 0.4 l/t and Selest Top – 07 l/t were high effective (76.2–96.0%) against seedlings pests. The most effective dressers (91–96%) against aphids and weevils were the chemicals BI-58 New – 0.7 l/ha and Borey Neo – 0.2 l/ha. The use of the mentioned chemicals for white lupin protection allows manage development and harmfulness level of harmful organisms in crops and prevent significant grain yield losses.
